I added a section on regression potential. Since I'm not that big of a coder, I can't really define the risk better than I did, but I hope that will do.
Thanks for the upload! Time for some testing then. ** Description changed: [Impact] jackd (jackd2) is unable to start when trying to acquire the same audio device used by pulseaudio. (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: + * 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.
