[Latitude E6510, IDT 92HD81B1C5, Speaker, Internal] fails after a while

[5c13nc3l4b]

all audio tests are heard. When I try to play music through rhythmbox, or from youtube no sound is heard. Alsamixer showes volume at 100%, nothing is muted, sound settings show that nothing is muted, volume slider resonds to the laptop button, but no sound is heard. Restarting the machine fixes it every time until I watch a youtube video then it breaks.
