Over the past few days I've been making a new PulseAudio module that detects the presence of JACK server, and adds a sources and a sink when JACK is started. Here are the notes: * This version uses JACK's dbus interface to detect server being started or stopped, i e /usr/bin/jackdbus instead of /usr/bin/jackd. If you use qjackctl to control the server, make sure that you check the checkbox "Enable D-Bus interface" under Setup -> Misc. * It is deliberately named module-jackdbus-detect instead of module-jack-detect, both to emphasize the above, and to avoid name clashes with an imaginary (?) future module detecting whether headphones are plugged in or not. * The patch is against stable-queue. * It is probably ready for merging into the next version of PA. I'm saying probably, since during testing yesterday, I sometimes got segfaults. However, I believe these are related to something happening inside libjack when the server shuts down; since I can trigger the same segfaults even without my new module involved. That said; it takes fewer strokes with the module enabled, as you can just press "start" and "stop" in qjackctl until it happens... * A question is about the default; patch 2 here adds it to default.pa. Should "connect" default to true or false in such a scenario? I think it depends on whether we're aiming for just showing the user the possibility (connect=false), or if we're aiming for a just-works experience (connect=true), which might upset a few people who don't want it to work that way...I've gone with connect=true as the default to mimic the behaviour of module-jack-sink and module-jack-source. -- David Henningsson, Canonical Ltd. http://launchpad.net/~diwic -------------- next part -------------- A non-text attachment was scrubbed...
