asterisk users - Aug 2005 - problem with sound device

I am getting this whenever I start asterisk.
Aug 15 15:03:58 WARNING[11754] chan_oss.c: Read error on sound device:
Resource temporarily unavailable

This is my sound card:
Multimedia audio controller: Fortemedia, Inc Xwave QS3000A

I am not sure... what I am doing wrong.
Please help.

Thanks,

sounds like your soundbard is blocked by another program. Sometimes 
applications like KDE or XMMS block the sound card, even after these are 
turned off. It then takes a while for the soundbard to become available 
again.

No, I don't have KDE installed.

Today, I have chaged sound card.
Now I have this one:
Multimedia audio controller: Ensoniq 5880 AudioPCI (rev 02)

Still I get the same WARNING message.

BTW, where can I know more information about /etc/asterisk/alsa.conf

Thanks
