I don't know whether or not you specified the sound module settings in 
the lts.conf file, but I have at least 50 of the GX1's in our building 
working with sound and if you use this setting it might work. I have 
some terminals that auto configure, but most of my equipment is so old, 
it has to be specified in the lts.conf file:

This is the sound configuration for the default lts.conf settings at the 
beginning of the file:
        # enable sound by default
        SOUND              = Y
        # choose either esd or nasd to be the default
        # SOUND_DAEMON       = "nasd"
        SOUND_DAEMON     = "esd"

        # default sound volume
        VOLUME             = 100
        ### For ISA sound cards, you have to specify the module to use:
        # SMODULE_01       = "sb io=0x220 irq=5 dma=1"

Then I have to specify the sound module for each GX1 because it cannot 
auto configure like the newer machines:

#GX1 --
        SMODULE_01="cs4232 io=0x534 irq=5 dma=1"

Hope this helps.
