I have installed Tumbleweed(LXDE) and trying to setup my usb headphones as well(Microsoft LX-3000). I can see alsa recognise them fine, but whatever I try(like setting the headphones as default sound device) nothing is happening. I am bit noob regarding sound setup in linux, so please let me know which debugging info might be useful to find the solution.
Here is what aplay’s output looks like:
sudo aplay -Lnull
Discard all samples (playback) or generate zero samples (capture)
