Sound not working

[Martin]

I've just installed Hardy and after installation sound worked fine. But now it just stopped working without any changes having been done by me.

Here is some info:

After hard boot sound works again, but not on soft boot.

After one of the updates sound is now working all the time. You can remove this bug.
