Sound problem with Sarge (2.6.7) on IBM IntelliStation

[cedric <04@ga-fl.net>]

Hi,
I recently installed Sarge on my computer. Everything work fine but the
sound.

I have the following log in syslog:
Mar  9 22:17:57 localhost kernel: isapnp: Scanning for PnP cards...
Mar  9 22:17:57 localhost kernel: isapnp: Card 'Crystal Audio'

Mar  9 22:17:57 localhost kernel: cs4232: Must set io, irq and dma.

The "standard" beep work when I'm in a terminal window but I can't get
playing any other sound under Gnome.

Could anybody help me? I don't know what to do and where to search...
Regards
Cedric
