Public bug reported:
Gnome error sounds do play, but sound output from Firefox and other
applications doesn't work unless they can support a non-ALSA sound
driver. E.g. mplayer makes no sound unless the "-ao sdl" or "-ao openal"
parameter is added. ALSA and PulseAudio don't work.
Reloading the ALSA kernel modules doesn't fix the problem.

No HDMI device is currently connected, but one was a few days ago. There
have been several suspend-resume cycles since then.
I expect that rebooting will clear this issue, however obviously that
shouldn't be needed with Linux.
