Description of problem: gnome-volume-control works, but if i choose Edit -> Preferences i see lots of duplicated channels (Master,Tone,Bass,Bass,Treble,Treble,PCM,PCM ...). If i select just one of the channel (PCM), next time the program is opened i find two couples of faders and both PCM channels selected in Preferences. If i deselect one i find no PCM faders and no channel PCM selected in Preferences. It only affects ALSA devices (not OSS devices). Version-Release number of selected component (if applicable): gnome-volume-control from gnome-media-2.16.1 How reproducible: Open gnome-volume-control and look at Edit -> Preferences Steps to Reproduce: 1. open gnome-volume control 2. select ALSA device 3. look at Edit -> Preferences Actual results: Lots of duplicated channels found. Expected results: Find just one PCM, one Bass, one Treble ... Additional info: I have got an Audigy 1 (emu10k1) from Creative Labs.
