Public bug reported:
Binary package hint: pulseaudio
For the past two days or so, my AudioHub is missing from the PulseAudio
applet's Volume Control section and audio plays though the laptop
speakers.
This only after the laptop 'wakes' from an auto suspend after its
programmed 2 hours of inactivity. Previously, the sound defaulted to the
internal speakers after waking, but it was possible to re-select the
AudioHub via the Volume control.
The only way to re-enable the AudioHub is to reboot. Lgging out and in
does nothing.
