Bug Description
After upgrading to ubuntu 11.10 from 11.04, when headphones are disconnected the sound returns back to speakers. But if you try to reconnect the headphones, they no longer work (or sometimes they work for a couple of seconds and then nothing...).
This is a regression, in as much as it used to work perfectly fine in 11.04. Now I can see bug 870360 and bug 871633 pretty much stipulate the same problem, but I couldn't really relate exactly, based on the comments therein.
Temporary Fix
Under Sound Preferences -> Output -> Connector, when you plug your headphones, switch the connector to "Analog Speaker" instead of the current selection ("Analog Headphone").
So for some reason the alsa driver mixes up the Speaker and Headphone output state, and when Headphone is selected the speakers are functioning, while when Speaker is selected, the headset is functioning. This didn't happen in Natty 11.04.
Another thing to note is that my audio card has 2 outputs, one for Headphones and one S/P DIF for connecting external devices. S/P DIF works fine in all cases, no problems there.
