Another bug in gstalsamixer.c:

If an alsa track has both, capture and playback volume, channels for this track
may be counted wrong:

gstalsamixer.c:139: 'channels' initialized to 0

   gint channels = 0;

gstalsamixer.c:166: 'channels' used for counting capture channels

   if (snd_mixer_selem_has_capture_volume (element)) {
      while (snd_mixer_selem_has_capture_channel (element, channels))
        channels++;

        [...]
    }

gstalsamixer.c:179: 'channels' used for counting playback channels without
being reset to 0!!!!

    if (snd_mixer_selem_has_playback_volume (element)) {
      while (snd_mixer_selem_has_playback_channel (element, channels))
        channels++;

      [...] 
    }
