Summary:                    type dmix produces noise, type plug slave.pcm "dmix"
does not on SB EXtigy
Description: 
I recently noticed crackling sound when using the dmix plugin. While the
simple case { type plug; slave.pcm "dmix" } works, { type dmix; slave.pcm
"extigy" } (where extigy is the pcm for the card) produces a crackling
sound. (I observe the same problem with my build in ICH4 card, but AFAIR
this has been reported already).

I have tried a variety of buffering and period settings that I found in
various documentations on the web, but all attempts were unsuccessful.

At the moment, when the extigy is not connected, I am not able to reproduce
any of the distortion on the INTEL chip I was talking about. Strange
indeed. Once I get back to the extigy, I will report back, if the error
surfaces again.

Now that I tested the setup again, I am unable to reproduce this issue. I
am not sure what caused it and will try my best to reproduce it and give a
more detailed explanation on what caused it. Unitl then, I think the issue
can be closed.
