David Henningsson (diwic) wrote : Pulseaudio sometimes forget to set ALSA volumes

This is a meta-bug for the following problem:

PulseAudio does not update the volume at ALSA level. You can verify this by running alsamixer and see that the volumes do not change in the expected way.

This can happen in the following cases:
 * You switch ports (e g unplugging headphones, but speakers remain silent), and there is no information in the module-device-restore database
 * The PulseAudio volume before and after switching port is on the exact same level
 * You increase the volume while the actual sink/source is closed.

SRU Justification:

[Impact]

This seems to be a quite common problem. Result is usability problem and confused users as the volume appears to be correct, but is not.
