Doom 3 demo: snd_pcm_writei failed: Broken pipe
 

After I start new game everything goes fine and after 2-4 min the screen freezes and the game starts going with about 2 frames per minute.I hit "esc" and after 3min i see the menu and it's fine. When I return to the game the same problem continues.

I tried OSS instead of ALSA. The same thing happens .

I have no problems with other games that use ALSA or OSS.
