This is the sound chip I use for the GX1's is:

        SMODULE_01="cs4232 io=0x534 irq=5 dma=1"

These are the settings I use for the little diskless workstations from 


The Dell GX60 needs to be set to this:


Some old ancient Vectra's that we have use this:

        SMODULE_01         = "sb io=0x220 irq=5 dma=1"

Most of the time LTSP automatically detects which sound module to use, 
but if it doesn't, then so far these are the settings that I have found 
to work.

This would be a typical entry in the lts.conf file for a classroom. I 
use the lts.conf file for inventory purposes and to track down machines 
in the building in the event users are doing stuff they shouldn't be 
doing.... I have a hodge podge of machines, but prefer to look for 
donated Dell's with PXE capability. My current favorite is the small 
profile Dell GX60 - 240's as they are plentiful and easy to configure, 
sound works well. You can buy them pretty cheaply or get them for free 
from computer recyclers. They are fairly small so they don't take up as 
much room as the older desktop CPUs. Not quite as hot.


#Machine 55 -- Sarah's Room
        SMODULE_01="cs4232 io=0x534 irq=5 dma=1"

#Machine 56 -- Sarah Bayer's Room

#Machine 57 -- Sarah Bayer's Room
        SMODULE_01="cs4232 io=0x534 irq=5 dma=1"

#Machine 58 -- Sarah Bayer's Room
        SMODULE_01="cs4232 io=0x534 irq=5 dma=1"
