Bug description:
After some random time from starting Firefox it is no longer able to play flash sounds correctly. For example trying to watch a YouTube movie results in the video pausing a second or so into the playback. After about half a minute the video resumes and a stuttering sound appears (sound buffer looping over the first second or so of actual soundtrack). Scrolling controls work fine and the interface is responsive. Stuttering sound continues through the whole movie occasionally changing to some random 1-second sample of the soundtrack.

OSS is not loaded. Neither esound nor pulseaudio daemons are installed or active.

During the hang other applications have no problems playing the audio so the device is not locked. Even aplay works.
