Are you talking about the soundblaster emulation in the
BIOS using VSA? We have worked very closely with National
Semiconductor (for some Geode-related projects) and have
figured out that 8-bit sound will not work correctly with
the current OSS/Free sb driver (which probably is what
your JVM trying to use). The patch is very simple:
Look for the part on DMA buffer where it is defined as
64K, change it 32K (or any size less than 64K) and your
sb driver will now work for both 16-bit and 8-bit
emulation.
This is due to some mistakes in VSA code and hopefully
NS will release some updated code for BIOS updates.
