>Description:
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

>How-To-Repeat:
Just use the soundcard. It`s happen all the time when play music.
