How do I completely and utterly disable these?
sound_join=
sound_leave=
I have quiet=yes but thats part of the user profile not the bridge profile.
I don’t want to use silence/1
Create your own, shorter, silence file.
Bah. It’s frustrating that quiet isn’t honored in this case 
Ive decided to just do this:
sound_join=null
sound_leave=null
It throws an error of course because null doesn’t exist but its not catastrophic so…
Would be nice if you could just do ‘no’ or something to stop these.
