Duplicate PulseAudio sinks on startup

[badosu]

After startup, with Cadence set to start at boot, sometimes the Pulseaudio bridge created duplicate sinks:

~ ❯❯❯ pacmd list-sinks
3 sink(s) available.
    index: 0
        name: <alsa_output.pci-0000_00_1f.3.analog-stereo>
        driver: <module-alsa-card.c>
        ...
  * index: 1
        name: <jack_out>
        driver: <module-jack-sink.c>
        ....
        properties:
                device.api = "jack"
                device.description = "Jack sink (PulseAudio JACK Sink)"
                jack.client_name = "PulseAudio JACK Sink"
                device.icon_name = "audio-card"
    index: 2
        name: <jack_out.2>
        driver: <module-jack-sink.c>
        ...
        properties:
                device.api = "jack"
                device.description = "Jack sink (PulseAudio JACK Sink-01)"
                jack.client_name = "PulseAudio JACK Sink-01"
                device.icon_name = "audio-card"

Both output sound correctly but this creates issues with some other places that assume that jack_out is the only sink present.

This usually is because Pulseaudio creates an Pulse-Jack bridge when it recognizes a Jack server running, and Cadence is doing the same thing.

Try unchecking the Bridge autostart box on Cadence:
