Running Xubuntu 12.04 (64bits) I have a USB audio headset that sometimes doesn't show up in pulseaudio after unplugging and replugging.
The USB device shows up on lsusb, but doesn't show up in the volume control of pulseaudio.
Kill and restart pulseaudio:
The service should automatically restart after a few seconds.
Code: Select all
$ killall pulseaudio
