I have a usb mic (Samson GoMic) and I want to use module-echo-cancel with it.
But module-echo-cancel does not switch to new source after mic pluged in so module-echo-cancel have to be loaded after.
So I try to load this using udev rule.
Here is 95-usb-mic.rules:
ACTION=="add", SUBSYSTEM=="sound", ENV{ID_VENDOR_ID}=="17a0", ENV{ID_MODEL_ID}=="0305", RUN+="/usr/bin/pactl load-module module-echo-cancel use_master_format=1 aec_method=webrtc aec_args='\"analog_gain_control=0 digital_gain_control=1 noise_suppression=1\"' source_master=alsa_input.usb-Samson_Technologies_Samson_GoMic-00.analog-stereo source_name=samson_go_cleared"
ACTION=="remove", SUBSYSTEM=="sound", ENV{ID_VENDOR_ID}=="17a0", ENV{ID_MODEL_ID}=="0305", RUN+="/usr/bin/pactl unload-module module-echo-cancel"But the problem is pulse, that creates sourse after rule executing.
"pulseaudio -v" output:

TAGS=:power-switch:So is there way to execute rule after pulse creates source or tell pulse to make source as module-echo-cancel is loaded?
Ofc I could use a sh script with sleep and wait for a pulse, but I belive there is a proper way to do this.
