https://bugs.launchpad.net/ubuntu/+source/linux/+bug/84505/comments/30 Let me elaborate. * Alsamixer works right. It controls Master, Master Mono and PCM. * Unity Sound control and multimedia keys are completly broken. Detailed description: Open a terminal and run alsamixer. Starting from Mute (Alsamixer slides: Master=0, MasterMono=0, PCM=0) 1st press on VolumeUp -> MasterMono=51, PCM=25 2nd press onVolumeUp -> Master=4, MasterMono=100, PCM=56 (Believe me, Sound Sucks!) 3rd to 10th -> Master 16, 28, 40, 51, 60, 75, 87,100 (However GUI slide still at around 60%) 11th to 16th -> PCM 60, 70, 75, 81, 93, 100 Now AlsaMixer shows: Master=100, MasterMono=100, PCM=100 Let press VolumeDown: 1sto to 6th presses-> PCM=93, 87, 81, 75, 65, 60 (??) 6th press -> Master=93, PCM=56 7th to 14th -> Master=81, 70, 60, 47, 34, 22, 12, 0 (At this point GUI slide shows around 10%, however PCM=65 and MasterMono=100) 15th -> MasterMono=28 !!!, PCM=10 !! 16th -> Mute all As you can imagine Unit y volume control and volume multimedia keys are unusable on this computer.
