2.6.0: alsa, esd, mpg123

2.6.0: alsa, esd, mpg123

on my debian (unstable) laptop newly running 2.6.0, i've noticed
an irritating tendency for music to not pause, but instead to
try to go too fast, skipping small parts of the song (fractions
of a second).  this results in music with regular beats sounding
erratic.

i'm using gqmpeg -> mpg123-esd -> esd -> oss -> alsa (maestro3).

switching esd to use -tcp instead of -unix seems to alleviate
the trouble a bit.  ogg123 playing through esd doesn't seem to
do it as much either.

has anyone else noted this problem and tuned it away?  thanks.

Unless esd has ever gotten fixed, esd doesn't handle errors or write() 
return values.

Some sound cards can't handle the flood of data and only accept so many 
bytes at a time.  Esd does a write of 4K, only 2387 bytes (this is an 
example) are actually written.  Esd doesn't pay attention to this and 
starts writing with the next 4K chunk.  This leads to the skips.

On slow machines or slow kernels you don't notice this (as much), on 
faster stuff, it's very apparent.

For what it's worth, there is hardly any error checking at all in esd.

this patch built and the modules install just fine, but when i
try to play music, i just hear garbage beeps and blips.  that's
with or without esd.
