Re: [Alsa-devel] intel8x0 driver motorboots (gets caught in loop)in Quake 3

check /proc/interrupts during the playback whether the number of irq
10 increases.

During the looped sound, the number of interrupts increases by about fifty a second:

josh@spleen:/proc$ date; cat interrupts | grep SiS
Thu Feb 13 11:41:10 CET 2003
10: 64806 XT-PIC SiS SI7012
josh@spleen:/proc$ date; cat interrupts | grep SiS
Thu Feb 13 11:41:20 CET 2003
10: 65281 XT-PIC SiS SI7012

also, check the status shown in /proc/asound/card0/pcm0p/sub0 during
the playback, too.

Here are several polls taken a couple of seconds apart while the looped sound is playing:
