[Discuss-gnuradio] audio card sampling rate problem

Hi all,

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 gnuradio 
would determine the audio rates automatically.

Best regards,
