Hi Nathan,

One thing you might look at is https://wiki.gnuradio.org/index.php/ALSAPulseAudio

Hi Mike,

That's exactly what I was looking for, thanks.

However:  I swapped out the USRP source for an osmocom source, and it
seems to be "mostly working" but the audio comes through like the adults
from the old Charlie Brown show from when I was a kid.  Instead of
clearly-intelligible speech like I can hear through GQRX, using gnuradio
I can only get speech that sounds like "mwah mwah mwah mwah"

Attached is a .png of my flowgraph, hope it's not too large for the list
(about 100kB).

Appreciate any advice anyone might have.
