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.

We have a bunch of these and used them for years and they're flawless and reliable. One we use to connect a PC to a TV, one to connect a PC to a speaker system. The third one I used (along with the Hifime UR23 SPDIF Optical to USB Converter) to construct a USB-to-TOSLINK-to-USB cable to connect my two Windows 11 laptops, then enabled "Listen to this device" on the Hifime on the receiving device. This let me listen to a perfect digital mix of both devices at the same time. It works great out of the box, no settings changes needed, no software or special drivers needed, no noise or hiss or ground loop, no audible latency, no volume reduction. It's perfect.

Works great, but the cable feels cheap.

Worked great for 24 months, now completely dead. :(

I broke the SPDIF out on my brand new 600 dollar motherboard. 600 bucks for a motherboard is absurd, so is the crap quality of the SPDIF port that crumbled when inserting an optical cable for the 1st time! Rather than try to fight it out with the manufacturer (MSI) and rebuild my whole computer around a new board, I found this USB to Optical dongle. No drivers, plug and play. Optical out in a snap. I'm using the optical out from my computer's usb to my AV receiver (DENON 2700) and it works great with full volume control on my computer and volume control on the receiver. For 20 bucks, this beats an expensive headphone or audio DAC in a heartbeat. The optical end is beefy and not fragile at all. I have see some complaints about this and it seems pretty robust to me...at least the one I got. I suppose if you want to hang an engine block with it, it will probably fail. IDK, it works great and I'd buy another one if the same scenario for me presents itself.

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.

Plugged it into a mid-fi Integra I had lying around, and it just worked, giving an otherwise out of date home theater receiver but still high end amp a well deserved extension on life. Most awesome solution. Highly recommended, inexpensive solution for excellent sound at your workstation and/or laptop.

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.

Without any other driver installations or anything, it was found and properly worked instantly
