Well, as the message says - we request an 8 bit channel - and the
card gives us a 16 bit channel. Since the higher levels of the SL
library were only written to accomodate 8 bit samples, we are unable
to proceed.

    "Need a sound card that supports 8 bits per sample."

...what part of that message is unclear?

I suggest you complain to the author of the OSS driver for that sound
chip - it's ludicrous that it should be unable to deliver a simple
8 bit monophonic sound channel.

Short of an almost total rewrite of SL, there isn't anything I can do.
