Comment 7 for bug 84505

It appears that on my Dell Inspiron 9300 with Ubuntu 7.04, the front panel volume up, volume down, and mute buttons affect ONLY the "Master" track. However, sound output uses both the "Master" track (Front left and Front right channels) and the "Master Mono" track (Mono channel). For example, pressing the mute button will mute ONLY the Master track, leaving the Master Mono track at it's previous volume (which sounds terrible :\ ).
