Sorry for the delay in replying. I booted up Sarge to see how I had the sound 
set up, and got distracted.

Your lsmod looks ok, but I see on my Sarge install I have 2 OSS modules 
in /etc/hotplug/blacklist. Some older kernels still had the OSS modules 
"audio" , and "usb_midi" in them, and it was necessary to blacklist them to 
prevent them being loaded. If you run.
cat /proc/asound/oss/sndstat   you should see 2 lines saying something like.

Installed drivers:
Type 10: ALSA emulation

If there are no such lines, OSS is being used.

Also run lsmod to see if "audio" , and "usb_midi" are on the list.  If they 
are, su to root on the CLI, and with a text editor add both those modules on 
separate lines to /etc/hotplug/blacklist  without the quotes.

I must say I'm a bit short on ideas when it comes to laptops, as many of them 
have really cheapo soundcards, and some of which just don't seem to want to 
work on Linux.

Anyway have a look for those 2 OSS modules. At least will eliminate something 
else.

Nigel.
