RuntimeError: audio_alsa_sink

Greetings.
(Not sure that this message actually was posted, so I’m submitting a
second
time.)
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?
