GNU Radio can dump an audio source to a file sink.  You will have to play with 
sampling rates and word type. I saved a file of audio from a video I was playing 
to a file.  I had to use this:

aplay -r 48000 -f FLOAT_LE audio.wav

to play the file since the default source type was float.  sox can convert the 
file to other formats.

The audio source can be picked in pavucontrol ... maybe a monitor of your 
speaker output (if you are listening to the sine wave) or the module directly.
