how can I dump module-sine generated samples to a file?

best regards

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.
