OP25 OP25 DMR

[MTL_Emergencies]

I'm trying to create a channel configuration for a Tier II DMR channel using OP25 (Boatbod fork).
I'm not getting any audio but it seems I am getting sync (looking on the sterr.2 file, see attached).

This is what I'm writing on the terminal:

./multi_rx.py -v 10 -c dmr_channel_test.json 2> stderr.2
./audio.py -u 23466

I attached the configuartion file (.json) down below.

{
    "channels": [
        {
            "device": "rtl_0",
            "demod_type": "fsk4",
            "destination": "",
            "excess_bw": 0.2,
            "filter_type": "rrc",
            "if_rate": 24000,
            "name": "VC",
            "plot": "fft",
            "symbol_rate": 4800
        }
    ],
    "devices": [
        {
            "args": "rtl=0",
            "frequency": 447625000,
            "gains": "LNA:39",
            "name": "rtl_0",
            "offset": 0,
            "ppm": 0,
            "rate": 2400000,
            "tunable": true
        }
    ],
    "trunking": {
        "module": "tk_trbo.py",
        "chans": [
            {
                "lcn": 1,
                "frequency": 447625000,
                "cc": 1
            }
        ]
    },
    "terminal": {
        "module": "terminal.py",
        "terminal_type": "curses",
        "#terminal_type": "http:127.0.0.1:8080",
        "terminal_timeout": 5.0,
        "curses_plot_interval": 0.1,
        "http_plot_interval": 1.0,

        "tuning_step_large": 1200,
        "tuning_step_small": 100
    }
}

You're going to need a "destination" in the channel for the UDP audio.

"destination": "udp://127.0.0.1:23466",

I did just that but for some reason I'm still getting no audio.
I'm running Ubuntu 22.04 on a VM and I'm getting audio for other instances of OP25 (like P25 systems).

Actually I had to remove the trunking configuration and everything works fine!
