I find this stanza in /etc/pulse/default.pa
### Automatically restore the volume of streams and devices
load-module module-device-restore
load-module module-stream-restore restore_device=false
load-module module-card-restore
That seems kind of like it might be what I am looking for but not sure what would happen if I set it to true as it looks like it is going to do that to all sound devices. I may give restore_device=true today and see what happens.
