Well its right at least; SNDCTL_DSP_GETOSPACE is indeed not implemented in 
the es1371 driver.  I don't think this is really a problem though, as the 
emu10k1 driver doesn't implement it either.  Although thinking about it, I 
don't think I ever tried running MPlayer with the SB Live!  I know it works 
with the Media Player though.

Hmm, ColdFish doesn't do anything clever; if we're talking about the Ogg 
plugin all it does is read in data from liboggfile and write it directly to 
/dev/sound/dsp  It doesn't do any setup on the device (E.g. it does not call 
any ioctls() ) so this might be your problem; ColdFish is not setting the 
correct speed/stereo/format options.  Most Syllable OSS drivers default to 
44100/16but little endian with two channels, but the es1371 driver may not.

This is probably why cat'ting a wav to /dev/sound/dsp sounds wrong; the 
driver is set to a different speed/stereo/format than your wav data.

Hmm, well "Port to AtheOS  Sergio Lopez (xa...@gm...)" but SB 128's are 
pretty common cards; I'm sure *someone* must be using one!
