Hi all
I've got OP25 up and running on my ubuntu box, paired with a simple snd_aloop->darkice setup for private streaming. I'm running in to an issue where OP25, despite showing that it's still tuning and receiving traffic, stops outputting audio. No errors are displayed even with verbosity level 9, it just quits outputting sound altogether. A restart of OP25 fixes the issue but then after a few minutes it does the same thing again.
I'm launching op25 with the following command:
./rx.py --args 'rtl' --calibration=-100 -l http:192.168.0.151:8180 -N 'LNA:42' -S 1200000 -f 857.7375e6 -o 24e3 -O loop0 -x 2 -T trunk.tsv -v 7 -U -w
On the web gui, it's as if nothing has changed. The constellation looks good and it's still tuning to the various frequencies. Just no audio coming out, which I can verify by viewing the output of "arecord -D loop0 -vv".
There was a single time when it worked flawlessly for several hours. I did a system reboot to make sure it would work again and it went right back to the same issue. No clue how I managed to get it to work that one time.
I'd appreciate help on this. It's a headless ubuntu server 18.04LTS. The one thing I think could be happening is the lack of a real hardware soundcard messing with GNURadio's audio sink but I'd imagine that would be an easy fix. Just don't know how to implement it.
Thanks!
