Thanks Andrei.

"lsmod|grep snd" results in,

when I say "modprobe -r snd_usb_audio". It says "Module snd_usb_audio is
in use". I tried with "-f" option as well. Still cannot unload. Then I
tried to it again after "alsactl kill quit"; but still cannot unload.

Also "alsactl init" is producing some errors also. I shared in my
previous email. Copying here again for the context.

What other options may I try?
