Audio not working - Githubissues

Hi. I'm trying to use op25 on Artix Linux, with Python 3.10 and gnuradio 3.10. I was able to compile this fork and rx.py runs without errors, it seems to decode fine but there is no audio.

This is how I'm launching rx.py: ./rx.py --nocrypt --args 'rtl=0' --gains 'lna:36' -S 1920000 -q 0 -d 0 -v 2 -2 --tdma-cc -V -U -T file.tsv 2> stderr.2

And this is what the log says:

I noticed there's the -O flag but I was not able to get the audio to work... Is there a way to force it to use pulse audio instead of ALSA, maybe that would work better?
