Is some other application locking the sound card? An IM client, a media
player, even a browser? Also, are you in the relevant groups? (audio,
whatever)?

Incidentally, is your end goal to do something that involves sound? If
you're doing RF stuff alone and are only looking to test some basic GNU
Radio functionality, you might be better off skipping the ALSA issues
(which seem to be fairly common on this list and often difficult to work
out). You can use things like benchmark_tx.py and benchmark_rx.py to
test transceiver functionality, etc.
