After installing Precise on my PC, some problems with soud occure. While using Lucid there were no problems.

The sound is choppy and distorted in low tones range. As I absolutely have no experience in setting/testing and doing anything with Audo Devices I need help even to diagnose the problem.

update:

 sudo lshw -c multimedia

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.
