OP25 on a Raspberry Pi: 'gnuradio.op25' has no attribute 'fsk4_demod_ff'

[wgbecks]

Yeah, finally got this. I think by the end my brain was mush, but it seems to need 2.1.3 or I get a segmentation error, then for this I need to use alsa and drop the mean() (leaving just 'input), and ensure -O audio_out when calling rx.py

To direct audio to Liquidsoap from rx.py, you specify -w -V arguments in place of the -U and -O options.

For multi_rx.py, set the voice channel "destination": "udp://127.0.0.1:23456", and remove (blank out) sockaudio.py
from the audio section of your JSON file.

You can enable local speaker audio from within Liquidsoap by uncommenting the output.pulseaudio(input) down in the
LOCAL AUDIO OUTPUT section of op25.liq.

Keep in mind that you'll need to be logged in to a terminal to run Liquidsoap else the Pipewire/PulseAudio sub section
will not function "AS-IS" due to inherent permission levels. PM me if you have a desire to run OP25 and Liquidsoap as
system services (headless) and I will help you out with a few additional configs to make that happen.
