"pw_stream_set_active" Errors appearing in log, unable to select filter chain again.

[KynikossDragonn]

Using PipeWire 0.3.77 and OBS 29.1.3

I can't select my filter chain anymore. The plugin instead grabs the raw microphone device and the following shows in the terminal:

My filter chain conf: voicemod.conf.gz

Additionally; the plugin doesn't load if placed in ~/.config/obs-studio/plugins/ and only seems to load if placed in /usr/lib/obs-plugins/ but I can't find any reasoning for why this is occurring anywhere in the official documentation.

That commit seems to fix the error messages, but it still wont connect to the filter-chain:

It sees the chain in the device list and let's me select it:

Helvum shows otherwise, the plugin is going directly to the microphone itself and not the filter chain:

Even when I change it back and forth from "Blue Snowball" to "Voice Modulation Source" it's reflected in the log, but it's constantly being forced to the wrong device anyways:

This used to work perfectly fine so I don't know what changed or what's going on. Other PipeWire things I've been using have been able to properly select the filter chain, and it's properly selectable in OBS's PulseAudio backend (but it used to crash wireplumber entirely when I tried back then)

Do I need to change something in my filter chain configuration file? Does anything in this block look incorrect?

capture.props = {
    target.object = "alsa_input.usb-BLUE_MICROPHONE_Blue_Snowball_201606-00.mono-fallback"
    audio.position = [ MONO ]
    audio.channels = 1
    node.name = "effect_input.filter-chain-voicemod"
    node.passive = true
}
playback.props = {
    audio.position = [ MONO ]
    audio.channels = 1
    node.name = "effect_output.filter-chain-voicemod"
    stream.dont-remix = true
    media.class = Audio/Source
}
