no sound after resume

[Matteo Dell'Amico]

Hi!

After a suspend/resume cycle with HDMI plugged in, it seems that pulseaudio doesn't recognize anymore the internal analog device (speakers/headphones) and I hear no sound. Before suspend I see two audio sinks through "pacmd list-sinks" (internal analog and HDMI), and after resume I only get HDMI audio. Still, audio only ever comes out of the internal device.

A "killall pulseaudio" solves this for me (i.e., I get audio from the internal device).

This looks a bit similar to the old bug #202089, but I don't know if it's the same.

If this still affects you the Fix wasn't enough. Passed on to further examination.

Reverting to "New" awaiting confirmation by another "affected" user.

Hi! Since this bugs continues to happen on my computer, I wonder if there's anything I can do to confirm it and give you more information about it...
