Thanks Andrei. I followed the following steps: 1. Found that it is pulseaudio that is blocking the module unload. 2. systemctl --user stop pulseaudio.socket 3. systemctl --user stop pulseaudio.service 4. Verified that now nothing is blocking snd_usb_audio (using lsof) 5. Unloaded module using "modprobe -r" 6. Loaded again using "modeprob" 7. Started pulseaudio again Still the device is not listed in alsamixer and hence cannot play. "alsactl init" also producing same errors as before. Regards ~Pankaj
