Hi, quoting http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=452282 :

After upgrading to the latest version playing any file results in cracks during
playback. Downgrading all gstreamer0.10 related packages to the Testing version
fixes this problem for now. I’m using a soundcard with the CMI8783 chipset.


Below are the GST_DEBUG=5 logs with 0.10.14 and 0.10.15:

http://slomosnail.de/~slomo/temp/gst_0.10.15-1.log.bz2

The main difference I see is, that before 16 bit caps were used on the alsa
sink while with 0.10.15 32 bit caps are used:

intersection of the caps in 0.10.14:
