I have an older system working fine on the master branch and I'm currently
trying to set up a new VM running the max branch. The goal is to send audio
from two talkgroups to darkice. The problem is that I'm not getting any
audio out of rx.py.
I know the darkice config works, because I can do this and hear pink noise
on the stream:
speaker-test -r 8000 -D hw:Loopback,0,0
But starting rx.py with the same audio device like this, I never hear
anything:
./rx.py --args rtl=0 -N LNA:42 -f 774081250 -S 1320000 -v 5 -2 -T
ss911_tacoma.tsv -O hw:Loopback,0,0
The receiver seems to be working. I can see the name of the talkgroup I'm
interested in at the bottom of the screen while it's active, I just don't
hear anything on the stream:
"""
NAC 0x1e1 WACN 0xbee00 SYSID 0x1e7 774.431250/804.431250 tsbks 2390
voice frequency 773.431250 tgid(s) 40306 40107 0.3s ago count 77

Frequency 774.431250 Talkgroup ID 40106
PCSO East

Is there something obvious I'm doing wrong here?
P.S. Is there a better way to pipe audio to darkice than snd-aloop?
