Hi everyone! Recently, I've upgraded Ubuntu from 10.04 to 12.10, and this little audio problem keep bugging me since day one I've upgraded it. I've followed all the tips from this blog to solve my audio problem. I think I've solved it. But, everytime start my machine, I've to insert "killall pulseaudio" to reset my Dummy Output to normal ones. Tips anyone to overcome this pesky bug? Thanks!
