I saw a report that this was fixed in kernel 3.3, so you may want to try that.

Aspire 6920G. Same problem. Infuriating and brand new to Precise.

If I boot up with the headphones already in the port, the sound only comes out of those. However, removing them doesn't make the sound switch to the speakers, as it used to and as it should.

I updated the alsa package and the bug seems to be fixed already.

Could you please specify to which version you updated? I have alsa-driver (1.0.25+dfsg-0ubuntu1) installed which is the latest version on precise and the bug is not resolved for me (there was no update since Feb 16). I have an Acer Aspire 6930, too.
