Ubuntu: Stuttering Sound

Symptoms
Stuttering sound
Sometimes the sound just doesn't and some times it does

Possible Reasons
I have seen odd sound effects sometimes on older hardware. I Believe as of 8.04, the Ubuntu team moved to "PulseAudio" instead of ALSA.

PulseAudio is still in development to support older sound hardware. Yet ALSA still supports the old.

Resolution
Switching Safely from PulseAudio Back to ALSA (Ubuntu Karmic)

Run the following commands in this order:

$ sudo apt-get purge pulseaudio gstreamer0.10-pulseaudio

Code:

$ sudo apt-get autoremove

Code:

$ sudo apt-get install alsa-base alsa-tools alsa-tools-gui alsa-utils alsa-oss linux-sound-base alsamixergui

Code:

$ sudo apt-get install esound esound-clients esound-common libesd-alsa0 gnome-alsamixer

restart your computer!
Final Thoughts
It does kinda improve the sound quality, yet u may need to tinker with the PCM and Master volume to get the stuttered lowered to almost nothing.
