When playing sounds with alsa sink using any gstreamer application sound
conversion is done wrong and result on cracking sound. VLC seems to have the
same problem.

original GStreamer bug report:
http://bugzilla.gnome.org/show_bug.cgi?id=436192

upstream alsa-lib bug:
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3360

POssible workaround for gst pipelines is to add this before alsasink:
 audio/x-raw-int,width=32,depth=32 ! audioconvert !
audio/x-raw-int,width=16,depth=16

Another option is to use:
alsasink device=front

as my gconfaudiosink (so muine and rb plays ok)

Maybe it would make sense to patch alsa-lib 1.0.14 on fc7 to revert that change
or to upgrade to a fixed version.

Comment 1 Martin Stransky 2007-10-15 12:39:40 UTC
Is it fixed in 1.0.15rc3?

If you create a patch for 1.0.14 I can put it into F7 but generally this issue
has to be fixed in upstream...
