Audio output problem on asus eeepc

[Henri-Pierre Charles]

Hello, I have tried to use FreeBSD on a eeepc, 
the sound device is recognized :

eeehpc:~/>cat /dev/sndstat 
FreeBSD Audio Driver (newpcm: 32bit 2007061600/i386)
Installed devices:
pcm0: <Intel 82801F High Definition Audio Controller> at memory 0xf7eb8000 irq 5 kld snd_hda [20071129_0050] [MPSAFE] (1p:1v/1r:1v channels duplex default)
eeehpc:~/>dmesg |grep pcm
pcm0: <Intel 82801F High Definition Audio Controller> mem 0xf7eb8000-0xf7ebbfff irq 5 at device 27.0 on pci0
pcm0: [ITHREAD]
pcm0: <HDA Codec: Realtek (Unknown)>
pcm0: <HDA Driver Revision: 20071129_0050>

but I get some "buzzzz" every 5 or 8 seconds which are very annoying. Any
idea to resolve this problem ?

(I have tried oss from http://www.4front-tech.com/ and it works great).

H-P
