I have verified 16-bit operation using "pcmio" and it seems to work. Have used realaudio with my cs4237 and given the sound quality it seems to work in 16-bit mode... > The new bios I have (AMI 8/2/97) has an option to choose between PNP > aware/non-aware bios...

Would using pcm1 in the kernel instead of pcm0 do the trick? no apps should use dsp0 etc, they tend to use /dev/dsp which is a symlink to dsp0. You change the symlink to dsp1 and you are set (same for mixer, audio, dspW...) Cheers Luigi
