I do however have problems with audio playback, with Sonic Visualiser (SV) reporting that it is not able to open an audio device. What I do: ---------- * I start qjackctl, and start jack, with no appearant errors. * I start SV, open a new session, and import an audio file. (So far, I have tried mp3 and wav.) The file is displayed, and an notification box pops up, with the text "Could not open an audio device for playback. Audio playback will not be available during this session." The output from SV (all of it included further below) says that -------------- ERROR: AudioJACKTarget: Failed to connect to JACK server WARNING: AudioTargetFactory::createCallbackTarget: Failed to open JACK target -------------- There is no sign of anything related to SV in the qjackctl "Connections" window nor in the "Messages" window. What I'd expect: ---------------- I would have expected SV to connect to the running jack without any problems. Especially since other programs (timemachine, hydrogen) seems to connect without any problems. (I am able to play back with hydrogen.) Questions: ---------- Why doesn't SV connect to jack? Am I doing anything wrong? What should I try next?
