(jackd1 is currently not able to acquire the card through dbus). Users are often unable to use jack at all, without disabling pulseaudio. [Test Case] * First, make sure a pulseaudio client is actively playing audio through pulseaudio * Start qjackctl. * Select the same device that pulseaudio is using. * Start jack. Sometimes it takes a few attempts for the bug to appear. Eventually, jack will not start, and an error message like this will appear: ATTENTION: The playback device "hw:0" is already in use. Please stop the application using it and run JACK again[0m [Regression Potential] The fix adds code that deals with reserving the card for pulseaudio, so if there's any regression, it should be around that functionality. To my knowledge, that would only come to play in dealing with jackd, which is the most likely application to try unreserve pulseaudio reserved cards. Also this patch is taken from upstream, and thus already tested and working in 13.04 with no related regressions reported.
