That was probably me.  I also get devices building and found, but they 
produce no sound.

George Reid has suggested that some kernel magic may be necessary.

I'm using the following bits in the config file:

 # stabbing at sound

options         PNPBIOS
device          pcm
device          csa


The last two are needed; I can't tell a difference when I use PNPBIOS 
or not.

IBM also lists it as soundblaster pro comaptible.  Is this a direction 
worth exploring?  On my older thinkpad (755c), it would emulate 
soundblaster (it had funny hardware, too).

Another stray thought:  there's a couple of models which ibm with 
redhat linux.  Does sound work on those?


hawk, stumped (but quite grateful for george'shelp)
