It's the gstreamer-alsa plugin that is probably causing the crackle.
There are several bug reports in Gnome bugzilla. If you are using dmix,
you might want to look at this one:
http://bugzilla.gnome.org/show_bug.cgi?id=314689
There are a few others, but the general solution is to either downgrade
the gstreamer-alsa plugin or switch to using OSS instead of ALSA (which
is what I did). If want to do this in Gnome, go to the Multimedia
Systems Selector in the preferences menu, and switch the Default Output
Sink to OSS.
OSS does it too, even worse than ESD. The only one that seems clean is ALSA. Now I guess my next question would have to be is there a way to remove the dmix middleman and still get software based mixing? Also would putting in Jack potentially fix the problem?
