Usually this means some other app is hogging the sound card.
Open a console and run 
$ lsof | grep dev 
and see if something suspicious turns up.

If not, strace audacity:

$ strace -o aud.trc audacity

and after you got the error message, close audacity.
Then have a look at that trace, especially "open" calls:

$ grep -i open aud.trc | less

Search in there for "dev" occurances and see if they look like they should.

Do you have more than one sound card? ran asoundconf? is oyur sound hardware 
capable of hardware mixing?
