Public bug reported:
Hi, I use Lucid (10.04.3 LTS) on a Fujitsu Esprimo P5731 quadcore
machine with Intel HD Audio with ALC633.
I cannot turn off the internal speaker. There is no setting to turn it
off, and it does not go off by itself when external speakers are
connected, as with the Windows driver.
The hardware setting is set to "Analog Stereo Output", and Output is set
to "Internal Audio Analog Stereo". As a connection I can choose between
headphones (then all speakers are off altogether), Analog Output and
Analog Speakers. There is no difference between the latter two. Both the
external speakers and the internal speaker sound at all times...
Because of the poor quality of the internal speaker, that easily clips,
and it being monophonic I want to turn it off, but there is seemingly no
way to do this...
