Description pantzer 1999-10-17 16:10:01 UTC 
splay plays mp3 at low speed. The problem is that it tries to set stereo 
but gets mono.

SNDCTL_DSP_SETFMT now resets the AFMT_STERO bit. This was not the case in earlier kernels (from 990901 for example)

How-To-Repeat: 
Run splay.

For the record, this fixes a problem I had with my GUS PnP Pro and
pcmplay(1), which comes with tosha.  It set stereo before setting the
format, and the result was what sounded like low speed.
