Skype - problem with sound device

[Zbigniew Komarnicki]

Hello,

I have also problem with skype. When I try call to friend then I obtain 
following message: 
"Problem with sound device".

When I run skype from console I get the following message (when I call):
"/dev/dsp: Device or resource busy"

On my Debian I haven't such problem. 

I also change, 
sysctl hw.snd.maxautovchans=8

as was in previous message about skype, but still is the problem with sound 
device.

From 'dmesg', I have:

pcm0: <nVidia nForce2 400> port 0xb000-0xb0ff,0xb400-0xb47f mem
0xe8001000-0xe80 01fff irq 21 at device 6.0 on pci0
pcm0: <Avance Logic ALC655 AC97 Codec>

If you need more information I send it to you.
Please for help.

Thank you in advance,
Zbyszek
