I posted this in another thread. This way I've been able to easily get rid of Pulseaudio on Karmic:
Unfortunately the approach of disabling Pulseaudio has some - if you're lucky only minor - adverse effects. For example the audio applet will stop working (you'll have to adjust your audio settings using alsamixer in a terminal), the sound settings won't open any more and additional applications, which rely on pulseaudio being present, might just stop working as expected or completely.
Disabling Pulseaudio in Ubuntu 9.10 is pretty straighforward:
Code:
echo "autospawn = no" > ~/.pulse/client.conf
pulseaudio -k
If you want to reenable it:
Code:
rm ~/.pulse/client.conf
pulseaudio -D
Make sure you're not overwriting any settings you might have made to your user's PA client.conf, using the commands above. I rely on it being empty/non-existent, which it should be on a vanilla karmic.
