since you are using Ubuntu, the easiest way is to follow their
instructions to solve sound related problems and report it to them using
`ubuntu-bug audio` [1]. There are several developers working for(?)
Ubuntu who will probably be able to help you really quickly.

The developers prefer it, if you attach it to your message to the list.
But you can also *additionally* upload it to the ALSA site.

The developers if they have time. I guess for this it is better to bug
them on the IRC channel.

Sorry, I do not know.

I am sorry to not be able to help you right away.
