Public bug reported:
when I first did a clean install of Ubuntu 11.04 amd64 my usb microphone
(Microsoft) was recognised right away and worked flawlessly. (front panel) I
then removed usb mike and plugged in patch cord to my stereo receiver. No sound
at all. I know this isn't a hardware problem since windows works perfectly. (I
triple boot: Windows 7 pro_64 and Windows XP Pro. with Ubuntu).
I tried several fixes suggested in Ubuntu forums with no luck.
