StarTech.com StarTech USB Sound Card w/ SPDIF Digital Audio & Stereo Mic - External Sound Card for Laptop or PC - SPDIF Output (ICUSBAUDIO2D) - Lydkort - 24-bit - 96 kHz - stereo - USB 2.0 - for P/N: MU15MMS, MU6

I bought this for use with the Raspberry Pi 3b+ and experienced occasional issues with playback (muted/crackling sounds for some tracks). After experimenting, I figured out that this only occurred for a 96khz input, and when I forced input at 48khz the distortion(s) went away. Testing similar outputs on a £6 usb product showed that this issue did not exist there. Startech support states that the device is not supported for Linux even though almost all USB audio card nowadays are driver-free. I did not test this exhaustively on a windows PC as this error might only be reproducible on resampling. Caveat emptor - if you are buying this for a raspberry pi/linux kit! Additionally, sound output is muted on the linux/pi, compared to the £6 kit, or the on-board 3.5mm output. I couldn't be bothered spending a few weekends debugging the thing and have returned it (If I wanted a DIY kit I wouldn't be going for a USB solution!).

I had experienced problems with an internal sound-card. This solved the sound problem and all I had to do was plug it in. Very good and audio quality not bad for the money.

Very helpful product. When my computers built in audio out port stopped working i thought "oh no what am i going to do" then i found out that i could get one of these and when i got one i found it worked really well and aswell as getting my audio working it also made the quality much much better!!!

Does what is says on the tin. I needed a cheap external device to plug my headphones into as I was getting lots of static and interference from my computers onboard headphone sockets. Using windows ten I was able to simply plug this in and it worked with no setup or drivers to install (this may be different on older versions of windows). Sound quality is far improved with no trace of interference and music on my computer (especially 320kbs files) sound far better. A nice plus is the spdif output on the rear in case I want to add surround sound in the future. Great product so far.

Really does do stereo at 96khz with SDR and seems to be 24 bit resolution. Nice and small.
