Disable JACK autoconnect in Mumble 1.3 and later
I used to have to patch the JACK patch to make Mumble not auto-connect to the standard outputs. With JACK being officially supported in Mumble 1.3, that's no longer the case. Instead, you have to modify the config file by hand.
In ~/.config/Mumble/Mumble.conf
:
It's a standard ini file, so look for a [jack]
section. If one doesn't exist, create it:
[jack] autoconnect=false
And you're good to go.
