Bug#726556: pulseaudio: mic is dead after suspend

[Stefan Krastanov]

Hello,

I have just updated to the most recent debian testing. It runs pulseaudio 5.0.

The problem is still present.

3 pacmd outputs are attached:

- just after resume (mic does not work)
--- with gnome-sound-recorder running
--- without any sound recorders
- just after jiggling the volume bar on the microphone (mic works)

And one pulseaudio -vvvv output:

- starting pulseaudio (mic works)
- suspending and resuming (mic does not work)
- trying to record with gnome-sound-recorder (mic does not work)
- trying to record again after killing gnome-sound-recorder and
starting a new instance (mic does not work)
- closing all gnome-sound-recorder instances
- jiggling the volume bar (mic works)
