Regression in Mumble 1.3.0_3

[Max-FT]

System

• xuname:
  Void 5.6.2_1 x86_64 GenuineIntel uptodate rFFF
• package:
  Mumble 1.3.0_3

Expected behavior

Mumble starts up in a second or so (on a SATA SSD)

Actual behavior

Significantly delayed start up, due to mumble trying to connect to the JACK daemon when it isn't installed w/ output

Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel
exec of JACK server (command = "/usr/bin/jackd") failed: No such file or directory
Cannot connect to server socket err = No such file or directory

Steps to reproduce the behavior

Upgrade to mumble 1.3.0_3

Looks like Mumble 1.3.0 always tries to connect to JACK on startup regardless of backend settings.
Seems this was fixed upstream in mumble-voip/mumble#3990 in master.
I'll try patching 1.3.0 with this change and see if it fixes the problem.

EDIT:
I wrote some sed to set bJackStartServer and bJackAutoConnect to false, unfortunately this does not seem to stop Mumble trying to connect to jack on startup regardless of the backend setting and if jack is even installed.
For now it seems best to revert #20840 or make it a template option (off by default) for jack users like myself.

Sorry for the breakage.
