I have been experienting with gnuradio for some time and I have noticed
an annoying problem
with the audio sampling rate: in the scripts from the example directory
it is set to a hard
value of 32ksamples/s. However, my laptop audio card (or its linux
driver) do not support
this speed, only 44100 or 48000. So when updating to scripts from new
gnuradio source it is
always necessary to adapt the values in the scripts. Is there some way
how to ask the alsa
system about supported audio sampling rates from within a python script?
I guess there can
be more users with such limitations and it would be nice if the final
would determine the audio rates automatically.
