Yes, "Toslink" is inferior to HDMI, but fibre optic (in general) is *far* superior to HDMI. It's a shame they never updated Toslink. Fibre basically has no limit on cable length, is immune to EM interference, has much higher bandwidth, and is very cheap to make. Plus, no licensing fees need paid to the HDMI forum. Example: in networking, copper wires (like HDMI) can only support 10Gb bandwidth and max out at 100 meters (if you lucky). Fiber can support >100Gb and max length is measured in kilometers. There is a reason all telco and cable ISPs are installing fiber now. It surprises me that 30 years later, fiber cables haven't taken over everything. The only thing they cannot do is carry electricity. Image how nice it would be to use only the mini-Toslink connectors instead of HDMI that are big, often expensive, and must be inserted one way. Mini-HDMI and Micro-HDMI exist, but they are more fragile and can still only be installed one way. Yup, Toslink is inferior, but fibre is not. Here's to hoping someone introduces a fiber standard to replace Toslink, HDMI, and all the others.

I agree, we need a new, faster audio-only interconnect standard. It doesn't necessarily need to be toslink or even optical, just something fast enough to carry about a dozen channels of uncompressed audio (for some future-proofing). It's not efficient or economical to use a standard that's video centric (HDMI) to just carry audio signals. In a lot of ways, it'd actually be better to use copper cables. With copper, custom length cables and in-wall installations are much cheaper because you don't have to have a specialist to install the connectors on the ends. They're also more flexible and easier to run, which saves time and cost. They could easily start using USB-C cables to interconnect audio devices. USB-C can do up to 40Gb speeds (USB4). CAT8 network cables would also be an option, since they can do 25Gb to 40Gb, depending on the run length. They would be extremely cheap to implement, and they could use different connectors so that there'd be no confusion with accidently plugging them into networking devices.

@@ckought69 You're right that terminating fiber at custom lengths requires specialized tools and some practice. Maybe someone can invent an inexpensive DIY kit for home users. The problem with USB-C is the severe length restrictions. Shielded Ethernet 10Gb+ cables (CAT6a/7/8) are very bulky and pricy. Glass fiber cables are much thinner, more flexible, and more durable than most people expect. They are skinnier, lighter weight, and more bendable than the average USB-C cables I use to charge my phone. I think this hypothetical fiber A/V standard should support dozens of channels of uncompressed audio AND stereo 8k@120hz video. This way it can be an audio cable, video cable, or both. I'd like it to be a replacement for all other digital wires including HDMI. But it'll never happen because HDMI is too entrenched and is "good enough". Maybe when we exceed the limits of HDMI, our new optical format can take over. But the HDMI people will probably scare people by saying things like, "if you don't baby the wire, it'll break". It's not _that_ fragile. Ask any telecom worker. I've personally taken a spare wire and tired it in a knot as tightly as I could, and it still worked; I stretched it very hard, and it still worked. To "break" it, I had to kink the wire, smashing the bend completely flat with a pair of pliers. But once I undid the kink, it started working again.

I love that the guys says it's incapable of "lossless audio" of more that two channels. ADAT uses the exact same fiber optic cable and can transmit 8 channels at up to 24 bit 48khz. It's not the cable that is the limiting factor, it's the S/PDIF format.

To be fair; you'll not get a consumer TOSLINK supporting device that supports anything but SPDIF.

HDMI ARC/eARC almost always introduces random handshake/lip sync/input switching/device power issues. On paper, it sounds great, but it rarely works without a hitch in practice (in my experience, of course). The only quality upgrade ARC offers over optical is the ability to carry DD+ and DD+ Atmos, which is still lossy. Yes, eARC will carry lossless audio, but that's only relevant for Blu-Ray or UHD Blu-ray Discs. If you're really concerned about getting lossless audio for discs, then you should have a proper A/V receiver that handles your input switching and just passes video along to the TV. if you have a high-end soundbar, it should have HDMI ins so you can connect a BD player and proper streamer (Apple TV/Shield/Roku Ultra) to it, so again, you don't have to fuss with ARC/eARC.

I called Samsung for support no help also fails on a HDMI connected sound bar. So still issues out there with HDMI.

I learned something today. Thanks! 😁

Thanks @Chris! I had no idea and your video explained Toslink VS HDMI really well.

Thanks for the info. I had been using TOS Link because even though my sound bar says it is 4K capable I would have trouble getting it to pass the 4K video through it all the time. So I hooked the video source to the TV and sent the TOS link audio to the sound bar. So I just watched your other videos about how to correctly hookup the HDMI cables and use ARC. So long story short, now my video source is still hooked to my 4K TV, but I use the HDMI ARC connection to get the audio to my 5.1 surround sound system.

Optical has been a necessity for my new soundbar. I went from an old, classic AV receiver to a sleek LG Dolby Atmos soundbar and it sounds fine on 2ch and Dolby 5.1 content enough low end for me. But when I played any Atmos encoded content, 4k/streamed, for some reason LG forgot to process the low end audio into the speakers so it sounds tinny. Through HDMI/arc there is no way of changing the audio encoding on Disney+/netflix, but if I play through optical, the TV only outputs 5.1. Sorted the low end. It has upfiring Atmos speakers which I was not too impressed with so I don't mind sticking with just 3 channel Dolby digital audio.

Really the most compelling reason to use HDMI over Toslink is reduced cable clutter. Modern toslink supports 125Mbit/sec bandwidth. Dolby Atmos tops out at 18Mb/s (truehd lossless) and DTS-HD Master Audio is closer to 25Mb/s. Both are well below the limit for Toslink. The catch is if you're using Atmos, Dolby limits truehd to HDMI. If it goes over Toslink or coaxial S/PDIF it will use the compressed codec.

The issue is that the industry spec for TOSLINK has never been updated. Sure, the technology of optical has as it has other uses beyond audio, but the entertainment industry never heavily invested in it because by the time home theater became affordable and more mainstream, HDMI had come along and was a more versatile standard, as it could handle lossless 5.1 and 7.1 audio, along with video, and even an internet connection (though very few devices actually used internet over HDMI). There are very few devices and manufacturers that support lossless/uncompressed audio over TOSLINK just because the manufacturing costs of the chips to do so is so high, because they're not mass produced. 99% of the audio devices out there can only deliver a compressed signal over optical because of the old, inferior specs that the industry never bothered to update. So rather than getting Dolby TrueHD or DTS-HD Master Audio, you're just getting their lossy versions, Dolby Digital at 640kbps and DTS at 768 kbps.

There are plenty of non-4k capable pre-TrueHD receivers that will only support the lossy Dolby codecs.

Thanks for the advice! I didn't realize i wasn't getting the full surround sound with the optical cable.

I just got a soundbar for my LG CX, the optical connection means that the TV volume setting is shown on the screen just like the internal speakers. When using the HDMI/ARC it just shows a +- on the screen and the little display shows the volume increments which I can’t see from my viewing location.

Depends on what source you're using. If you're using a PC, then running HDMI from your GPU to a receiver or a soundbar and then out from that to your display creates input lag, and for HDMI 2.1 you have very few options right now, all of which are pretty expensive.

HDMI and optical both have ups and downs. I use HDMI for streaming and regular TV, and optical for my Xbox. It just works best that way.

Thanks for the upload. Hm my theater box is really old and is connected with the tvs headphone jack. I noticed both have toslink ports but the box has no hdmi. Do you think i get better sound if i go buy a toslink cable and pop it in? Those are 2 big speakers.

Thanks for information,I do have questions for you My tv digital audio out. Is broken the front it's come off . The little piece square How to connect my Sony sound bar without using the optical plug .

Optical was a quick and easy way for me to get audio from my desktop PC to the AV receiver. HDMI wasn't an option so one has to do what they have to do. It's good to know that if HDMI output is available then that's the way to go. Thanks for the explanation.

I am doing the same thing because I couldn't find a better way. I do have an issue getting the sound started, for lack of a better word. When I first start my PC, or wake it up from sleep mode, I get no sound from my receiver/speakers. Even though my SPDIF is seleceted as the source on my PC, I have to re-select it to get the sound started.

I just aquired that samsung soundbar in your video and I hooked it up with optical. It sounds great. But now I'm excited to see how much better I can get it to sound. I don't use the surround speakers, so will it make a difference?

Your video came up on my watch list and I enjoyed your video..you came across as extremely knowledgeable and explained things clearly. You mentioned sound bars and I was wondering if there are any suggestions for lower priced sound bars that are worth purchasing?

I have not yet been convinced by any multichannel audio setup anywhere. I enjoy much more a setup that is basically a 2.1 and the effect is even better on 3d glasses kind of movies. The most important is to have good signal, good level, clarity, and align audio delay with picture. Check polarity, ant surface reflections, distance between the wall floor and speakers. When all is good, tested and measured, the impact, the punch, the depth, the dynamic the 3D all this is better.

Next video should be: HDMI ARC doesn't always work....so use toslink.

Optical is fine for non atoms and stereo. In fact, depending on the quality of your stereo, it's better to use optical then ARC. There are lots of audiophile reasons this is true, but it boils down to running your pure digital signal through the comparably dirty environment of your TV's circuitry.

Another thing to consider with HDMI is that it’s all digital. In the old analog days, copper was subject to interference which resulted in people buying Monster-type cables to reduce the interference as much as possible - or go optical where possible. With digital, you either have a connection or you don’t. If you do, your ones and zeros result in picture and sound - no need for high-end cables that cost too much. If you don’t have a connection, then no sound and no picture - also no interference - there’s just nothing.

Everything interacts with each other and can create “noise” and introduce that into the signal. Yes, a digital cable will work or it won’t but your audio quality with HDMI will very greatly. Highly recommend trying to attend an Audioquest Cable demo. To this day I’m absolutely amazed at how much MORE audio details you can hear with better quality cables that introduce less “noise” into the signal. It’s jaw dropping for me.

This seems to be an engineering issue, there's no reason besides funding that optical audio could not be made to support Dolby Atmos. It can be done it just depends on who wants to do it.

Everything is an engineering and funding issue. The thing is there's no reason to do it. The HDMI interface is still not fully saturated, and there are no benefits to optical over HDMI as they are both a digital signal. In fact, you would need to move to an optical bundle system (multiple optical fibers in a cable or multiple cables) and have a bundle decoder (similar to the way fiber internet works) to get the exact same data that HDMI already carries on the other end. Hell, USB 3.0 can send more channels of data ,far cheaper, with zero additional R&D or engineering. The reason optical was created is because it came at a time before USB and HDMI and it was the only way to send digital signals from things like CD players or DVD players to DACs and receivers (or speakers with built-in DACs) this was done so you could get a bit-perfect duplication on the other side without a bunch of conversions to analog to digital and back again. In fact even old expensive DACs would often just passthrough analog signals, so if you used component cables, there was no point in a fancy DAC. The reason they still exist today is because of more legacy and audiophile hardware and devices such as the $800 dollar Martinez CD players that sound freaking amazing. The more expensive ones do use USB instead of optical. Sorry for the TLDR post, I just looked into all this and thought it was interesting.

@@tybera1114 The optical cable, itself, has no real bandwidth limitation. The limitations reside in the devices at both ends of the optical cable. Simply by changing to a full spectrum (multi-color fiber-optic transmission) pulse emitter and pulse detector would drastically increase data, and we haven't even talked about changing to modern pulse rates, across each light wavelength, yet. Improve the tech in the devices at both ends, and any TOSLINK cable can easily handle a massive data increase.

Thanks, man. Great info as I am using HDMI but was thinking to change to TOSLINK.

Hello Chris I just bought a Sonos home theater for my 75” LG 120Hz TV what’s your thoughts on this setup?

"Toslink" is inferior to HDMI, but fibre optic (in general) is far far far far superior to HDMI in pretty much every way. It's a shame they never updated the Toslink spec.

For audiophiles, it makes sense to use HDMI if they are very specific to the sound output they want like DTS, THX, Atmos, etc. but for majority average users, TOSLINK will do the work as well just as HDMI. I connected my TV to my Bose soundbar using TOSLINK. On the orher room, one of my older devices connected to my receiver with Bose surround speakers with TOSLINK.

Yes none of this applies to "soundbar users" but for folks with high end (5+ discrete speakers and an Processor capable of the lossless formats (Dolby TrueHD or DTS-HD-MA, for example), he's right.... while it's not a physical limitation of this cable type, all consumer home theater devices won't carry "lossless" 5+ channel audio over TOSLINK; you have to use an HDMI cable if you want that capability.

I understand what you are saying. Very likely the optical is the best connect for now. But now that I have a better understand ARC I will be reevaluating things when I add new Components.

Very helpful and now I must subscribe and watch more of your vids! You have a great speaking voice and you explained things so clearly. I have a lot of optical cables in my electronic box but never used them! Now I will have to investigate their use in some applications.

I see a lot of comments referring to fiber optic HDMI cables. Yes, fiber itself is incredibly useful for sending large amounts of data which is why I regularly recommend fiber HDMI cables. However, in this video I'm specifically referring to Toslink which has limited bandwidth compared to modern fiber connections. This is why I referred to it as Toslink instead of optical through most of the video. 😉

In the video you use optical , toslink and SPIDIF interchangeably. This is wrong . Even the title of your video on its face is misinformation. That optical cable is capable of extremely high data transfer rates . When it is used as an ADAT connection it can carry 8 channels of 48 kHz uncompressed audio . Many devices use the cable as SPIDIF which is usually a high bandwidth stereo configuration . On those devices it will be labeled specifically as SPIDIF. On other devices where it is labeled as “optical” you should refer to the user manual in order to determine the format that is native to the device . These devices are usually in a 5.1 uncompressed configuration by default. Sharing misinformation like this affects your credibility bro . Fix this quickly.

@@bayete1979 Yes, perhaps his terminology was a bit confusing, but Mr. Majestic is not wrong in essence because practically all equipment guides refer to "optical" and "TOSLINK" interchangeably. the bottom line is that most optical S/PDIF is limited to 3.1 Mbit/s and thus requires compression to transfer all the data we need nowadays, which means loss of quality. Meanwhile, you're a bit wrong -- not all optical cables are made the same and are of equal quality. The TOSLINK cable is designed for transferring LED light, not LASER. Some cables are plastic, others glass. As for optical HDMI cables -- they are indeed quite cool, but they won't change the quality in any way. Their use cases are fairly rare: 1) for extending to very long distances or 2) for environments with high interface, conditions you are very unlikely to have in a home theater. Actually, HDMI 2.1 does mean shorter copper cables, so perhaps we'll see more optical HDMI in use at home. Also, thank you Mr. Majestic for the "Toskink" typo, that made my day. :)

@Bayete Williams Thanks for your input. In this video I'm specifically referring to home theater audio. Adat doesn't really apply to this as I've never seen an adat interface on a piece of modern home theater equipment that supported lossless surround formats. This is also why I said "not to be confused with high fidelity stereo setups" which is a place where you'll commonly find toslink or adat (if you include professional audio equipment). I didn't use optical and spdif interchangeably in the video although i did oversimplify it considering most (if not all) toslink ports on home theater equipment are labeled as optical and use SPDIF for data transmission on the data link layer. Again, once you factor in the fact that that I'm referring exclusively to home theater and lossless surround sound like True-HD and DTS-HD, things like adat are irrelevant since they don't apply. I agree that I could have been clearer on this though. So I have added "(Toslink)" to the title of the video. But again, your concerns seem to apply more to professional audio equipment more than consumer grade home theater audio equipment. I appreciate your input. 😁

I really enjoyed your video. What is your opinion about Toslink vs USB? I was using USB but found out optical would have a cleaner signal like you said in the video.

Second thing I just ran into while typing this. I am support a LG C1 OLED as a monitor. Wouldn't technically using HDMI to Toslink (Astro A50 has optical) be the best of both worlds? A50 to C1 to Computer?

It the delay is perceptible there's something wrong somewhere in the chain, and it's not Toslink. I *have* experienced the players screwing up audio/video sync, but that's not a Toslink problem, that's a decoding issue.

I have the same toslink cable since 1995! not fragile at all! works great for my use cases...mainly hifi...

Something you may not have picked up on. ARC is Toslink (eARC is not). If negotiated through CEC source/sink capabilities comparison, the TV set's up a return path using IEC 60958 over a copper transport using the HEAC diff pair. It's just like having a Toslink cable included in the HDMI cable only using a differential pair instead of coax for common mode noise rejection.

I like what you are saying there but can you break that all down a little more there? I'm not sure I follow you on all of that.

Ok hears a tricky question for you: when using a smart projector (or smart tv i suppose)( im using a lg HU70LA) and streaming netflix, what cable method is best for audio out to your home theater receiver? Because your not sending video out to your receiver, arc hdmi cables arent an option right?

Correct...sort of. Optical cable CAN send multichannel hi-def audio losslessly. In pro audio, the ADAT standard sends up to 8 channels of audio at 24bit/48k max, and using the SMUX protocol it can send up to 4 channels at 24/96k. Unfortunately, Toslink uses the S/PDIF standard to move just 2 channel audio at up to 24/96k.

Thanks so much for explaining this to me. I've been hanging on to an optical connector for years now, and as it turns out, I should pass it along to someone else who can use it.

I have an older 5.1 surround sound receiver from the 90's and have seen the newer ones, but I'm not familiar with them. So just plugging the HDMI from my Bluray player and cable box into the newer receivers is all there is to it? No need for any coaxal or optical cables?

Wow. Had no idea that I was doing this wrong all this time. Thanks.

Thanks for the informative video. I checked and my Samsung TV does have ARC output, but my low end Samsung A430 soundbar doesn't have HDMI input. I am connected via Bluetooth, but the optical cable is connected as a backup. It still isn't easy to sync the audio to the picture.
