So this is the first version of Ubuntu that stops the sound from coming out of my speakers when I plug in headphones. Unfortunately it also stops the sound altogether... I would like to submit a bug report but I can't remember how, nor what program I should submit it for?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

I have the same problem and the bug is reported in here – user32662 Nov 7 '11 at 3:12

This question should have all the information you need about issues with alpha and beta releases.

In particular, this link covers how to report bugs.

As for what package you should file the bug report under, try to narrow it down as much as possible. If it only happens for specific programs, there's probably a common link between them. If all of your system audio is broken, I would file it under ALSA.

The asker would probably still like to know what package their bug will need to be filed against. – Christopher Kyle Horton Sep 2 '11 at 2:39
Good point. I've edited my answer. – Kris Harper Sep 2 '11 at 12:35
The bug should be filed against alsa-driver in Ubuntu (e.g., with ubuntu-bug linux-sound-base), not against the project ALSA or the project ALSA driver. (Bugs are categorized against source packages like alsa-driver, but ubuntu-bug takes binary packages as arguments, so it's necessary to report it against one of alsa-driver's associated binary packages, of which linux-sound-base usually makes the most sense.) – Eliah Kagan Nov 13 '11 at 2:55

Found a workaround (for a Dell notebook):

Add the following line to /etc/modprobe.d/alsa-base.conf

options snd-hda-intel model=dell-m6-dmic

'dell-m6-dmic' might be replaced with 'dell-m6' or 'dell-eq'
