[Solved] Thinkpad X250 - Sabrent USB audio input




New to Manjaro/Arch and having an issue getting audio input via a Sabrent USB soundcard. There is some input (via a mic) however it is very low and grainy. Output however is working perfectly!

I have installed pulseaudio and confirmed the levels are correct via pavucontrol.

Some system details below.

I was previously using Ubuntu where the device was functioning perfectly on Kernal 4.18. Which showed the device as below.

If anyone could point me in the right direction it would be appreciated.

Well after looking at this for a week I just tried to reinstall pulseaudio and would you look at that everything is now working.

Thanks anyway!


I didn’t know it was possible to reboot files, but there you go. :rofl:

"Have you tried turning it off and on installing it again?
