How can I replace pulseaudio with alsa?

I was wondering if there was an easy way of replacing pulseaudio with alsa. Pulseaudio is the biggest problem I am currently having with Ubuntu and I really want these problems to end.

If what you'd like to do is disable PulseAudio, the following steps should do it:

sudo sh -c "echo autospawn = no|tee -a /etc/pulse/client.conf"
touch ~/.pulse_a11y_nostart
sudo chmod 600 /usr/bin/pulse-session
killall pulseaudio

Note that you don't have to remove any PulseAudio-related packages to disable it.

If you'd like to temporarily disable PulseAudio, see the answer to the relevant question.

I suggest you try this tutorial to fix Pulseaudio : HOWTO: PulseAudio Fixes & System-Wide Equalizer Suppor

Just do the Part A and reboot, I have done this on several differents computer that have problems with PA and it have work all the times.
