duplicate 741825
I am going to mark this as a duplicate of bug #741825 for now, as you are like being bitten by the same or similar issues as outlined in that bug. If you really don't think your bug is the same, please feel free to remove the duplicate flag, however your chipset is the same as the chipsets referred to in bug #741825, so I strongly suspect you are being bitten by the same chipset bug. There is ongoing work with AMD to resolve this chipset bug, however there is no ETA.
The reason why audio worked in 10.10 and earlier but not in 11.04, is due to improvements made in the way the audio driver functions, however a side effect of this is that chipset bugs like this one are more likely to be exposed, which is actually not a bad thing.
