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.
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...
