Please help. I have a sound problem. Video and mp3 and general sound work fine, but when it comes to skype or Gizmo, the sound has problems. Whenever I make a call, the sound is like when you have 100% cpu usage and are playing an mp3 file, it has this buzzing noise. Like:

"He l l l l l oooo, Wel l l l coooo me to Sk y y yy pppeee tteeesst caaall"

Same happens in Gizmo. I tried both - ALSA and OSS (no idea what they mean though, I am a noob) and both have the same problem. When I look at the cpu usage when making a call, both programs are not using full cpu, they use very little - the normal usage. The sound is still choppy. What is going on?
