Hi,
Try to figure out what causes the stuttering:
- first, use simple players for testing (ex. aucat with .wav files, ogg123,
mpg321)
- make sure microphone/recording/whatever is enabled in the BIOS
- disable any BIOS options that could trigger CPU's "system management mode"
- possibly, try to disable wireless networking ("ifconfig down <ifname>)
- possibly, try to not start X (login on the console and use command-line
player)
If the problem persists, run:
audioctl; sleep 10; audioctl
during audio stuttering, check (and report) if play.error counter increases
