Newbie question: RuntimeError: audio_alsa_sink


#1

Greetings.
Got gnuradio compiled, made, and actually ran the dialtone test last
night.
However, when I attempted the same this morning, I got the following
message
(which, I have to say, I’ve gotten before but thought last night’s test
had
eliminated).
Any thoughts?

The error reporting is unfortunately not as specific as it could be.

In my experience, the most frequent cause of the above is that the sound
card is in use by some other application, possibly a previous run of a
GNU Radio application that didn’t exit cleanly.
