Thanks for the info. Marking as Confirmed and giving this to the
developers, as there should now be enough info to get this debugging.
** Changed in: linux (Ubuntu)
Status: Incomplete => Confirmed
** Description changed:
Steps to reproduce:
Play music
(Sound comes out of speakers)
Plug headphones in
(Speakers switch off, sound now comes out of headphones)
Reduce volume to 0, or just mute
Increase volume, or unmute
Expected results:
Speakers remain off, sound comes out of headphones.
Actual results:
Speakers come back on, but sound also plays out of headphones. The master
control controls both the headphone and the speaker volume.
snd-hda-intel in linux 2.6.28-11-generic in Ubuntu 9.04.
Bug stands since 8.04. Prior to that (with 7.10), the result was
different but also buggy in a different way (I don't remember the
details).
