I'm having a problem with the GstMixerTrack for PCM (ALSA). PCM doesn't support muting at all, but there's no way to detect this. Perhaps this information should be added to GstMixerTrackFlags. There's a related bug filed for xfce4-mixer on http://bugzilla.xfce.org/show_bug.cgi?id=4351. There's also a video demonstrating the problem with xfce4-mixer available on http://mykey57.free.fr/pub/tmp/mixer.ogv. (The mixer always assumes that a GstMixerTrack supports muting.)
Flags for this purpose have been added to GstMixerTrack recently (see bug #570832), but probably still need implementing in alsamixer. Changing bug title accordingly. Patches would be much appreciated (-base is freezing for a new release in the next few days).
The GstMixer interface has been removed in 0.11/1.0, without a replacement so far, and I don't see anyone jumping to add this to 0.10 at this stage, seeing that it hasn't attracted much interest in the last three years.
