Cubilux USB A to TOSLINK Optical Audio Adapter, Unidirectional USB Type A to SPDIF Digital Converter, S/PDIF Transmitter for Computer Laptop PC PS5/4 ONLY, NOT for TV Or Other Devices

This device works very well. My new PC had no SPDIF Optical out. Plugged this into a USB port and I now have crystal clean 24 Bit audio to listen to my music on the BIG speakers and my AV Amplifier. It's a more cost effective option than installing a PCI card in the computer. One minor issue: The first one I ordered had a short in the USB cable. The sound would stop under the weight of the Optical cable plugged into it. Hanging there caused a short. Must be manufacturing issue. Given the reasonable price, I just bought a second one and it works fine. Now I have two. One as a spare I guess. I can get the bad one to work if I hold up the cable in a manner to take the weight off the USB connecter. Strange issue, but I didn't bother to send it back. The cost of shipping wouldn't be worth it. It's a great product but needs better quality control in manufacturing.

I picked this up to improve the audio quality from my PC to my Samsung HW-S50B soundbar. Bluetooth just wasn’t cutting it, the sound was hollow, lacked bass, and didn't use the center speaker at all. This inexpensive adapter completely changed that. It was plug-and-play on Windows, I just had to switch my sound output from Bluetooth to SPDIF and I was good to go. Now I get clean, full sound with strong bass and much better center channel clarity. Movies and music actually sound how they should. Build quality feels solid too, no signal dropouts, and the optical connector fits snugly into my soundbar. The price is excellent for what it delivers, especially compared to some of the overpriced alternatives out there. If you're looking to squeeze better sound out of a setup that supports optical input, this adapter is a no-brainer over Bluetooth.

This works fabulously! Had to replace my 11yo PC build and lost the onboard SPDIF port I use to connect my DAC/Headphone amp. Only other alternative is a $100+ PCI card with ton of features I wouldn't be using. Saved a lot of money, and works great. Flawless installation, and Just Worked with Windows 11. No configuration needed other that switching Audio Output Device in the Sound settings. Highly recommend if using DAC with a laptop or any PC that doesn't port onboard.

Worked perfectly for using a Samsung 2.1 soundbar with wireless sub for a desk PC setup. No drivers, it was instantly recognized as a sound device in Windows 11. This soundbar made for TV is always ready to go and working when I need it to.

I used this adapter almost daily in my car for two years. I can't believe how badly this was affecting the audio in my system until I replaced it with a different USB to TOSLINK adapter on a whim. Immediately noticed a few nuisance peaks disappeared, and the mids and highs opened up and became less tense. I don't even know how this can screw up the audio so badly since it shouldn't have a DAC in it, but the results were night and day. I should have replaced this a long time ago. Properly designed digital/digital converters should not noticeably improve audio quality, but badly designed ones definitely will degrade audio quality. This is a poorly designed converter.

PC USB to Optical Cable to old Marantz AVR. Works perfectly for my 5.1 system.

Worked as described but didn't fix my issue. Used to connect a laptop to a mid 2000s home theater receiver. The laptop only saw it as a stereo output, couldn't figure out how to switch it to 5.1. Couldn't even make a custom bios for it. Could have been user error.

Works like it says on the tin, successfully transmitted 5.1 surround to my receiver, no mess, no fuss, no special drivers (Windows 11). For everyone that's noticed the broken power save setting (consistently cuts off the first couple seconds of audio after even a second of silence), this is a broken implementation of USB selective suspend. You can work around this by turning off USB selective suspend in power settings (Windows: "Edit advanced power settings" > USB settings > "USB selective suspend" to "disabled"). This stops the machine from putting any USB devices to sleep; may or may not be worth it depending on the use case. Would give this 5 stars if the vendor manages to patch the above.

Compré este adaptador para conectar mi barra de sonido Sonos Ray al PC y la verdad es que cumple perfectamente con su función.

En resumen, un producto práctico, fiable y totalmente recomendable si necesitas una solución para conectar por óptico desde un puerto USB.

Funciona mais ou menos. No modo 192khz ele as vezes trava, fica distorcido. No modo 48khz ele funciona sem problemas. Não sei se é problema no firmware dele, não sei se tem como atualizar, no manual não tinha nenhuma informação sobre isso, eu busquei informacao e diz que nao tem, entao o problema pode ser permanente.

Plug and play. Works directly without any software installation.

muy bien, me esta funcionado perfectamente!!

I'm using this to get digital audio out of a Raspberry Pi and into an SMSL SU-1 dac, and for that purpose it's exactly what I needed. I love how simple it is. I do think it's a tad expensive though, it's about the same price as an HDMI audio extractor which could do the same thing but this is a simpler device.. but whatever it works great. Side note: I've seen some reviews mentioning it doesn't work with Dolby or DTS. Although I haven't tried that, from what I know about optical audio there's really no reason it shouldn't work. It will not transcode your audio into Dolby or DTS though, as in it wont just output all audio that way. The software you're using must support sending those formats over optical audio (such as Kodi), and the file you're attempting to play must contain one of those audio formats. Once the software is configured to pass the audio through optical it should work.
