I can hear the sound but music isn't coming out

Hi!

I'm quite newbie with NetBSD. Anyway i have this strange problem. If I
start playing music it gives the first partial second out and stops
playing. Play sign stays still on. After that I can use slidebar and
change the spot where it keeps repeating that small part of song. MP3/Ogg
makes no difference.

I have compiled xmms from pkgsrc and the version is 1.2.10
dmesg tells about my soundcard

auvia0 at pci0 dev 17 function 5: VIA VT8235 AC'97 (rev 0x50)
auvia0: interrupting at ioapic0 pin 18 (irq 11)
auvia0: ac97: Avance Logic ALC202 codec; headphone, 20 bit DAC, 18 bit
ADC, Real
tek 3D
auvia0: ac97: ext id 607<AC97_22,AMAP,SPDIF,DRA,VRA>
audio0 at auvia0: full duplex, mmap, independent

This is Acer Laptop with AMD64 processor and the installation is diskless
So is it possible that this is some kind of weird NFS problem?
Although playing mp3 from DVD isn't workin either. Right now
I have no idea what is really wrong.
