Skype has been known to mess up the mixer settings. So disable the automatic configuration of the mixer controls in Skype: right-click with your mouse on the Skype icon in the system tray - Options - Sound Devices - remove the tick at: Allow Skype to automatically adjust my mixer levels. Click Apply. Then close Skype (right-click with your mouse on the Skype icon - Quit).
Here is something else I've noticed just now: If I have something plugged into the headphones port on the front panel (e.g., a set of headphones) everything works fine except that pavucontrol still thinks that the front headphones jack is the only port available. Sound comes out of both the headphones and the speakers, I can do a speaker test, everything. I'm beginning to think that the only problem is that, for some reason, the pulseaudio subsystem doesn't know that the backplane speaker port exists. ALSA doesn't seem to care whether anything is plugged in or not, so doesn't care about the second port (and may, in fact, not be aware of it either, but it doesn't matter).
Maybe we're wasting our time chasing the wrong problem.
I've been doing some Googling and found the following: https://bugs.launchpad.net/ubuntu/+s...io/+bug/946232. Then, I went down to comment #32 as mentioned in the bug description, opened /usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf (as root), commented out all of the "required-any" lines, and saved it. Finally, I rebooted, opened the "System Settings / Sound" control, and Voila: All was golden.
Now I just need to decide what to do next. Report it to Pulseaudio? Print off and save a copy of the above-mentioned bug report for future use? Forget the whole thing? Decisions, decisions, ...
Thanks for your help, aus9.
I tried the above on my Fedora 18 install, but instead of rebooting I simply killed and restarted pulseaudio. That worked as well.
