Almost certainly. The module-combine-sink can probably get a manual list of slave devices if you know the name of the physical sink, and it should also be possible to use `pactl move-sink-input <sink name>` instead to avoid the second bit of Perl munging. -- Arun _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
