NetBSD technet 3.0_STABLE NetBSD 3.0_STABLE (GENERIC_LAPTOP) #0: Fri Feb 24 14:52:18 UTC 2006 i386

When play music, mp3, wav etc. sound often interrupts and this line goes to log repeated many times:
auich0: fifo underrun

My machine is a laptop hp compaq nx6110. My soundcard:

auich0 at pci0 dev 30 function 2: i82801FB (ICH6) AC-97 Audio
auich0: interrupting at irq 11
auich0: ac97: Analog Devices AD1981B codec; headphone, 20 bit DAC, no 3D stereo
auich0: ac97: ext id 601<AC97_22,AMAP,VRA>
auich0: measured ac97 link rate at 48004 Hz, will use 48000 Hz
audio0 at auich0: full duplex, mmap, independent

Just use the soundcard. It`s happen all the time when play music.

Audio has undergone many changes since 3.0.  Please try an 8.0 beta kernel or a
NetBSD 8.99 -current kernel to see if the underruns still occur.
