Bug#804120: pulseaudio: iceweasel->Tools->Add-ons ... (silence)

[Kingsley G. Morse Jr.]

Hi Felipe,

Thanks for quickly drawing my attention to a
possible incompatibility with firejail.

That was it.

I'm happy to report that editing

    /etc/pulse/default.pa
    
from

    load-module module-native-protocol-unix

to

    load-module module-native-protocol-unix srbchannel=no

seems to have fixed it.

A few humble comments are inserted below...

Yes.

Yes, for once, you're right again.
