I bought a new Samsung TV that (surprisingly) did not include an optical audio port to connect to a standard Yamaha sound bar. This adaptor worked perfectly. I was able to connect from the TV USB port to the digital port on the Yamaha sound bar and started receiving quality sound in seconds. Very happy with the purchase and two thumbs up!

Product perfect for Sonos speaker. It was super easy to install and works well.

It functions as described, and it seems to be well made. I'm not sure about the price, but I'm thinking that it will pay for itself in time.

Did not know this existed- but a great way to add optical audio to your computer.

I've been hunting for a fiber audio cable to connect to my new smart TV in my fairly old amplifier after buying two or three that didn't work I finally found this and it worked

Would disconnect and create a lot of static..

initial set up was very easy. However, I noticed a different times that I get static between my sound bar and the TV. I usually end up disconnecting the USB and then reconnecting it and it seems to go away until the next time.

The package was delivered on the expected day. The adapter was better than expected. The package it came in was very good and it was a perfect fit for my sound bar. Excellent quality!

The media could not be loaded.

This cable is awesome literally plug and play!

Sometimes the audio can get a static feedback and you must unplug and plug it back in. The red side seems to be loose in my sound bar. Either way, my outdated sound bar is now working with my new tv.

I ordered the USB to optical S/PDIF adapter cable by GINTOOYUN.This product distinguishes itself from others as an all-in-one solution for running a cable from a USB port into an optical S/PDIF (Toslink) input. A separate USB cable, fibre optic cable, power adapter, and control box are not needed.This adapter is constructed with a thick, flexible cable much like you would find on a studio microphone. The signal converter is a nondescript cylinder in the cable about 30 cm away from the Toslink connector.The inline converter is built around a Texas Instruments PCM2704C DAC according to the lsusb command in Linux. That chip, descended from the very first CD player DACs made by Burr-Brown, has a maximum 48 kHz sample rate and 16 bit resolution, fairly modest in contrast to some of my DACs operating at up to 384 kHz with 32 bits. For reference, my preferred outboard audio device for analog output up to now has been the XtremPro X1 USB DAC, which is based on an ESS ES9023 chip rated for 96 kHz with 24 bits. However, I am more of a critical listener than a number chaser and typically run my computer audio at an unexciting 48 kHz.This USB to Toslink adapter does relatively little, accepting bits sequenced by the PC for USB, and translating them into light pulses according to the S/PDIF protocol. (The DAC module in the PCM2704C is not actually wired for output with this product.) When my speaker system plays with this cable, I am basically listening to the DAC in the speaker system. While my speakers have proven terrific with the XtremPro USB DAC and an analog wire, I was surprised they sounded equally smooth, powerful, and free of audio artifacts when fed by this new adapter. Furthermore, rapid A-B switching affirmed the digital line subtly improved subsonic and high treble representation without tonal shift elsewhere. Simply put, my very good speakers sound a tiny bit better now. I expect this GINTOOYUN product would support superb sound on the very best audio systems.Both Windows 10 and 11 recognized this device as a USB DAC and automatically selected it for output. Windows apparently has an S/PDIF quirk, insisting that digital output only be sent at full volume with no option for muting, volume reduction, or left/right balance changes. Luckily, the Sound Mixer Options (you can type the name in the Windows search menu) can reduce and remember volume for individual apps. Of course, you can also adjust the volume on your physical sound system or amplified speakers. The only problem is that setting your physical volume control very low may upset the frequency balance on your amplifier. (Setting an external amplifier high and varying the level by software usually sounds better for me.)The PipeWire audio subsystem can manage USB devices in Linux Mint 22 and Debian 12.8. The Sound Settings offered an output choice called Analog, which is similar to Windows with no master level control. Digital (IEC958) was another choice that allowed the system volume to govern the S/PDIF level like it does for every other audio device. Digital is my selection for regular use.For optimal sound, I set my speaker system for the loudest output I would want to hear (about 75% of maximum power). Then I adjust Linux from 20% to 80% (sitting around 50% mostly) for normal listening. This setup lets the computer climb to 100% without distortion or clipping, for testing purposes, even if I need to move away from the speakers to tolerate the loudness.This adapter is a straight lead from a USB port to a Toslink input, with no other cables or equipment required. It has made my music immune to external distortion and interference between PC and speaker. The sound is flawless for me so I positively recommend this product to audio enthusiasts seeking an upgrade to Toslink.

It works and I'm keeping it, but you lose Windows volume control using this thing. You have to adjust each app manually. It's a pain in the rear end for those of us (like me) who use the keyboard volume controls a lot. Still, it works and it solved a problem I was having so I'll take the good with the bad.
