As the title suggests I was able to get my thrift store 5.1 surround working perfectly with this adapter, it's a shame that the optical connector isn't a standard on more products, I'm using a Steam Deck with USB dock and it was plug and play after enabling the 5.1 surround option in my operating system, sound is perfect and the little dongle seems just fine!

Parfait pour connecter mon PC a mon ampli HC. J'ai un Denon AVC A11SR qui ne recoit que du SPDIF ou du coax je peux donc y brancher mon téléviseur et ma console mais pas mon ordinateur. Pour cela je passais via un DAC externe Cambridge que j'ai maintenant remplacé par cet adaptateur pour pouvoir connecter l'ordinateur directement a l'ampli et utiliser les DAC embarqués du Denon qui sont de bien meilleure qualité.Attention par défaut le flux est en 48KHZ mais la procédure pour le réglage est jointe dans l'embalage et on peux facilement paramétrer en 192KHZ et obtenir une très belle qualité.

Cubilux USB A to TOSLINK Optical Audio Adapter is a great little device, it gives me perfect 5.1 sound on Windows 10, Linux Mint and Raspberry Pi OS.I bought this to replace an old Soundblaster XFi card with optical output which connects a PC to my home theatre 5.1 surround sound system. The latest versions of Windows/Linux don't recognise the Soundblaster sound card, and this USB device was a simple solution which enabled me to upgrade the OS on the PC. It also opens the door to replacing the PC with a N100 mini and still connect with 5.1 sound.The device was recognised out of the box by Windows, Linux Mint and Raspberry Pi OS, but the key to getting it working was VLC media player with its multitude of settings, to enable the 5.1 signal to be passed through to the amp without any processing.Perhaps these details will help others:WINDOWSSettings / Sound / Output Device = S/PDIF Interface (USB Interface Adapter)VLC:- Force S/PDIF support = checked (also works unchecked)- Force detection of Dolby Surround = Auto- Output module = Auto- HDMI / S/PDIF audio passthrough = Enabled- Device = S/PDIF Interface (USB SPDIF Adapter)LINUX MINTSettings / Sound / Device = Digital Output (S/PDIF) USB AdapterProfile = Digital Stereo (IEC 958) OutputVLC:- Force S/SDIF Support = checked- Force detection = Auto- Output module = ALSA- Use S/PDIF when available = checked- Device = USB S/PDIF Adapter USB Audio Direct hardware device without any conversion- (or Device = USB Audio IEC958 S/PDIF Digital Audio Output)RASPBERRY PI OSAs above for Linux Mint, just select the USB device from the list with passthrough / no processingI've tested it on Windows/Linux Mint/Raspberry Pi OS with encoded 5.1 content (movies, TV, etc). I downloaded some samples which test all the speakers in turn to check it's all working, I'd forgotten how brilliant some of the demos are with sounds coming at you from all directions. I expect it won't work with PC game sound effects unless your PC can encode them into a 5.1 stream in real-time, but that's not my use case anyhow. It outputs stereo sound just fine too, I use Dolby Prologic on the amp to copy stereo sound to the rears in that scenario.While experimenting I couldn't get it working on Linux Ubuntu as the device list in VLC was empty, but I prefer Mint anyhow so that wasn't a problem for me. Time will tell whether it's reliable but so far it works great for my particular needs.

Appena collegato l'pparecchio è stato riconoscioto da Windows. Quindi una volta settato nelle funzionalita Audio del Pannello di Controllo, il flusso audio è stato regolarmente inviato attraverso il cavo ottico allo Stereo con successo

I plugged this device in and it started working immediately, however I was experiencing frequent audio drop outs and it was getting pretty frustrating. I read online the cable could be dusty, so I tried to clean both ends no to avail. I was almost at a loss, when I decided to try and mess with the audio settings in Windows. It was defaulted to 48 kHz sample rate, and I changed it to 96 kHz. That small fox seemed to make the issue go away entirely. So now I am happy with this device, though I'm not sure why it was experiencing this issue out of the box.

SO i just bought a new PC laptop for production and video editing. I used a older custom made one with original thunderbolt 3 and had ZERO issues using my 2 UAD Apollo X8P's and x twin quad core.problem with the new thunderbolt 4 and up drivers on PC is UAD is very lazy and will not do any work on fixing a bug they have in there source code when being used as a native playback engine.sooooo I bought this connected it into the x twin as a adat input and now native windows audios is tight very well clocked and has had ZERO issues.my DAW (nuendo) never had issues but once you would select UAD drivers as a native playback engine for lets say you tube it would crash the console software and you couldn't use your DAW. this completely bypassed the problem and now they work together flawlessly

Built a new gaming PC, but still rocking the old Z5500 Logitech speakers. New PC didn’t have the required optical out, so I ordered this adapter. It works flawlessly. Cheap, plug and play solution. Sound quality is great.

The review which mentioned this thing turning itself off was spot on. On Mac at least, if it isn't continuously receiving audio, it will shut itself off instantly, for who knows what reason. The receiving gear which is clocked to it (has to be) will then lose sync. When you send music back into it, the receiving gear will have to re-sync to its clock, which takes time and effort. Why they didn't keep it on I have zero clue. The thing doesn't waste tons of power or anything. It's a low-power LED bulb. Destroys functionality.The workaround would be to have a multi-tenant output mixer with a very low-level keep alive noise running on it. Which is hard to arrange. Really frustrating implementation blunder. Everything works perfectly otherwise, I tested up to 96KHz, no other issues. I probably end up returning this.

This can be a big money saver for PC (desktop) users because most PC's under $700 do not come with an optical audio port - forcing you to either use one of your display ports (just for sound), deal with a large converter box for the analog 3.5mm speaker out jacks that most PC's do come with, or use a bluetooth connection if available - which are always finnicky and don't always connect automatically each and every time. OR the big one - buy a more expensive PC that does come with an optical audio port.Instead, this adapter converts any standard USB port to an optical audio out port.Plug the USB side of the adapter into any USB port on your PC or other device you want to play music (audio) from, and then plug the optical audio side of the adapter into the optical audio port on your soundbar or other device. Make sure the sound settings on both your devices point to the new port, and you're done.I use my PC to play music through a soundbar and the sound is perfect - USB to Optical is all digital, so there's no analog converting. And, it was important that I could just turn everything on, hit play on my music player and it works, every time. No need to mess with settings each and every time, and no messing with bluetooth connections - which is another reason optical audio ports are better to use when you can.I've seen some reviews where the device gets hot, but it's been about a month now and mine is just fine and I use it all day, every day - lots of music.Time will tell, but either way, the concept will remain valid - as long as your audio/music player device (PC, laptop, tablet, etc...) has a standard USB port and your speaker device (soundbar, standalone speaker, transceiver head (for larger music setups)) has an optical audio port, then you can use devices like this one to play music between the two.
