Hi, I am using ubuntu 12.04.1 and I am experiencing a problem with pulseaudio. When playing music, video games or anything else that uses sound, every once in a few minutes the sound gets chunked for less than a second. I tried changing some bitrate configurations in pulseaudio's conf file, and that caused the chunking to be replaced with a buzzing sound at that moment.
Pulseaudio logs clearly show an error with 'snd_hda_intel':
But I don't know how to fix it. Any help?Code:( 349.592| 58.650) E: [alsa-sink] alsa-util.c: snd_pcm_avail() returned a value that is exceptionally large: 58256 bytes (330 ms).
