If users want to unconditionally switch to bluetooth as before this module does, he just pass "only_from_unavailable=no" or does not pass this argument. > > > > > > Under this situation, if we connect a bluetooth headset, the gnome > > sound-setting will list bluez input/output devices, but they are not > > active devices by default.

My patch just add a option to let pulseaudio to conditionally switch to sink/source, if users want the unconditionally switch as before, he can do it by setting the argument to no. > > > _______________________________________________ > pulseaudio-discuss mailing list > pulseaudio-discuss at lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss -------------- next part -------------- An HTML attachment was scrubbed...
