The USB sound dongle on this workstation has stopped working, but only for me. The system settings Audio setup window detects it but no sound is heard
Run "alsamixer" (it's a command-line tool) and in the text UI that appears, press F6, select your USB audio device, and then check if it's muted or the volume is 0.
PulseAudio generally uses the ALSA sound mixer to change volumes, but not always. For some devices, it uses a software volume control that doesn't use the ALSA volume controls. So if those are set to 0, there will never be any sound.
