The volume-meter in the GUI (xfce), as well as the volume- meters in alsamixer suddenly start toggling mute/unmute like crazy, and the levels also keep changing. Like if some weird ghost-user would be hammering the keyboard shortcuts in alsamixer... ;) After some minutes, the sound returns in the same fashion: crackles, stuttering and the volume-meter GUI going crazy. Does anyone else have this problem?
