Override ACP values locally

Hello,

I've been using pipewire on Arch Linux for some time now with great success, one particular issue has been bothering me as of late, and that's the distortion I get on calls when my 'Internal Mic Boost' is set to a higher volume.

The problem seems to go away after turning that down to 0% or so, but it doesn't seem to be a solution as it goes back up after changing capture volume, etc.

I asked on IRC and suggestions were to switch to soft-mixer on the device, which I tried, unfortunately without good results.

Another suggestion was to change /usr/share/alsa-card-profile/mixer/paths/analog-input-mic.conf in order to disable 'Internal Mic Boost'.

Would it be possible to override settings from analog-input-mic.conf in pipewire/wireplumber itself? E.g. under some config in ~/.config/wireplumber/main.lua.d.

If it isn't, is there another way to do this other than changing the files in /usr?

Thanks in advance.
