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

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