I tried this after deleting my ~/.pulse dir (I am not sure if that was
necessary, I guess I just assumed it was). Now gnome session starts up muted
but this time you can actually see a muted speaker symbol in the notification
area. Then it is simply a matter of raising the volume with the basic volume
control in the notification area. The settings seem to be automatically
recovered when I reboot and login again.

Also, Jan Steffens replied to my downstream bug report [1], he suggested
playing with pavucontrol/gnome-settings. I had tried this before.

After his comment I had another go with pavucontrol and started clicking
everything and suddenly I start getting sound again.

I reset my .pulse dir to find out what made the difference (delete .pulse from
console session and reboot, login to gnome).

It turns out I have to switch output "connector" (in gnome) or "port"
(pavucontrol) from "Analog Mono" to "LFE on seperate mono output" (whatever
that is!).

Now pulseaudio seems to keep the "good" setting where sound can be heared. It
seems that after changing this one setting, the master channel that was zeroed
and muted is now maxed and unmuted.
