After installing 12.04 Precise on my PC, I have encountered some problems with audio output which did no occur when using Lucid.
The sound is choppy and distorted in the lower tones. As I have no experience in setting/testing and doing anything with Audio Devices, I need help even to diagnose the problem.

Update 2
It has something to do with the volume. If the audio is quiet it is not choppy, if the sound is loud then it begins to be choppy.

Misery, I seem to have found a solution on my system using the same driver (different audio device though)
gksudo gedit /etc/modprobe.d/alsa-base.confAdd the following line:
Restart System
My audio seems to be working fine now. Full volume, flash content, videos, audio files. Let us know if it helps.
