micd: scale sound volume with ambient noise level (#26399)
* test changing sound volume
* test changing sound volume
* create system/hardware/pc/hardware.h
* implement Hardware::set_volume using pactl
* soundd: use Hardware::set_volume
* add sounddevice dependency
* sounddevice example
* simple micd
* cleanup
* remove this
* fix process config
* add to release files
* hardware: get sound input device
* no more offroad
* debug
* calculate volume from all measurements since last update
* use microphone noise level to update sound volume
* fix scale
* mute microphone during alerts
* log raw noise level
* hardware: reduce tici min volume
* improve scale
* add package
* clear measurements on muted
* change default to min volume and respond quicker
* fixes
