Description of problem: I want to use JACK as the audio device Version-Release number of selected component (if applicable): How reproducible: very Steps to Reproduce: 1. Start Control Centre 2. Select Sound/Multimedia/Hardware/Select Audio Device/Jack Audio Connection Kit 3. Actual results: I got a message box stating: Sound server informational message: Error while initializing the sound driver: Couldn't connect to jackd The sound server will continue, using the null output device. Expected results: I should be enjoying real time audio. Additional info: From the documentation it appears that the JACK daemon (jackd) should be started somewhere - KDE startup maybe?
My investigations show the jack could be used as kde sound engine only after starting it in other way. In other words, you should to start jack via initscripts or profile environment, or via QJackCtl (just install it by yum and start under X session). After jack is started you may choose the Jack as middle- end sound service. P.S. If you have some information with another description of the KDE and jack integration, you are welcome to reopen this bug. Also do not forget to add yourself into jackuser group to gain realtime priority.
You can call me picky in this regard! It just seems to me that the functionality that QJackCtl provides should be available as a KDE kcontrol page with a build-in ability to manage jackd just like artsd. Now that would be good KDE integration.
