No Audio Below 20% volume

Hey all, I'm having a minor issue with some audio. When I set my system audio to 20% or below, it results in no audio coming through my speakers. I do have my audio setup through my Arctis Pro Wireless DAC, so when my headset is not on it goes to my external speakers. This audio is handled by a USB connection. I've searched up around for the answer, but I'm not seeing anyone else with pipewire reporting the same or similar issue.

Is the DAC detecting the low input level as silence and disabling its output?

I've been testing and I doubt it as it wasn't an issue under Windows, but things can change.

The DAC is being recognized as a Headset due to the USB plugin though.

It would be worth removing the DAC and seeing if the issue persists with the built-in audio hardware.

[Solved]

Turns out it's an issue with the config file usb-gaming-headset-output-stereo.conf.

In /usr/share/alsa-card-profile/mixer/paths/usb-gaming-headset-output-stereo.conf I added

db-values = "0:-36  30:45"

I would love to explain how this works, but I genuinely have no clue how or why. Just going with it for now.
