Hi,

I recently installed Ubuntu Lucid after using Kubuntu Hardy LTS for a
long while (KDE 3.5.10).

I am trying to disable sound output to my internal speaker.

I have an HP DX2300 Mini Tower machine which has a full speaker on
board. There isn't a way to disable it in the BIOS without disabling
the entire on-board audio device, which I use.

In Hardy I found a way to tick all output devices in Kmix and then
dable the internal speaker.

I can't find the same in the Gnome Sound Preferences. When I turn off
the external speakers connected to the line out (green) plug of the
on-board card, the internal speaker continues to output sound,
actually it does all the time, but the external speakers mask it while
on....

This is really annoying. I am no stranger to the CLI, but I am not
sure which .conf to change and where to look - I don't know PulseAudio
that well. I tried to use alsamixer under CLI, but when I turned off
all volume to PCM, the master volume was also affected....

Help!

Thanks!

The best way to disable an internal speaker is to unplug it
from where it plugs in. Just follow the two wires to where they plug in
and unplug.
