>Organization:

>Environment:
DELL Latitude CPi D266XT
>Description:
Any try to play 11025 x N Hz (11025, 22050, 44100) via
/dev/dsp (using sox, mplayer, or even cp file.wav /dev/dsp)
makes a lot of noise. Looks like IRQ handling/buffering problem,
but in the same time 8000/12000/16000/24000/32000/48000
samples playing quite well. Bug remains the same since
4.6-RELEASE, 4.5-RELEASE/STABLE worked perfectly.
>How-To-Repeat:
Take a wave file, e.g. 11025Hz/mono and try to play it.
Could be easily reproduced using "play" script from SoX port.
>Fix:
The only 100% workaround is to put sound sources from 4.5-RELEASE into
source tree and rebuild kernel. Need some modifications of Makefile -
removal non-existent (in 4.5) sound drivers.
