This was plug and play on my Ubuntu laptop. I only use it for audio output and it works with plugging a standard headphone plug into it without using a TRRS adapter (however, if you accidentally select it as your input and go into Discord or something the other party will hear an interference sound). I havent used it with a TRRS but I suspect it would work fine and the inputs show up as options for me on Ubuntu as well.

works as expected

Item worked but the USB end of the cable has a metal cover that has come loose and is sliding. Cable is still work but this problem concerns me in that it might not survive as long as I would need it to.

Unit does what it supposed to do. The sound quality is much better than the old pin plug output. It solved my problem with a dying pin plug.

I bought a pair of very good Logitech speakers which I wanted to connect to my KVM switch so that they would function with both of my computers. KVM switch did not have a spare port to connect the speakers to. This adapter worked well to connect via USB port to the speaker set. Another problem solved!

It was easy peasy! I just plugged it into one of my USB ports on the back of my tower, plugged the jack into it, and then restarted it. That is all it takes to make it work! If you just plug it in it might not work. It didnt for me until I restarted it.

My sound card went out in my computer and found this and tired it and it does exactly what I needed I now have sound again...

My LG Ultrafine 5K display has no audio jack, and I did not want to have two cables to connect to my MacBook Pro. This product connects to a USB dock connected to the display, my speaker system connects to this adapter, and thats it. In System Preferences, this product shows up as USB sound device; when selected, sound from the Mac is routed to the speaker system via the product. Mission accomplished. Very nice build quality, attractive design, excellent warranty... and very reasonable price. So what is there not to like? Nothing! Highly recommended.
