audio cutting inand out intermittently

Binary package hint: pulseaudio

Notice a stop ad go audio problem. It seems almost like caching, pauses, then continues. while running applications with any type of streaming. from on-line streaming a video in flash, to playing a game in wine, or playing a game like alien arena. audio sometimes stops and freezes for a short time, then catches up, like it is off sync with that is initially on the screen. Other noticeable cases is on video and complete pause of the video for a brief 4 seconds, then continues.

From the logs, the following is appearing:
