I put the following command line into jack settings:
pactl load-module module-jack-sink channels=2; pactl load-module module-jack-source channels=2;pacmd set-default-sink jack_out
it is to be executed after jack service starts (but the same if before).
I see from the audio settings window that pulseaudio switches sink but the sink is not respected by applications that continue to use the old one. If I switch manually to another and then back to the sink I get the sink used by the applications as desired.
Why does this happen, how could I make the sink switch effective by the same command line so pulseaudio really switches and not just on the interface of the settings window?
Note: the sink pulseaudio is sent default at startup does not conflict with the jack output device, that is, it is not the same. (Fedora 18 Gnome)
Thank you in advance
