Hi, I'm trying to get a Jack DBUS setup working on Fedora 18. It seems pulse refuses to release the audio device when it gets a dbus request from jack: Sat Nov 3 20:08:11 2012: Starting jack server... Sat Nov 3 20:08:11 2012: JACK server starting in realtime mode with priority 60 Sat Nov 3 20:08:11 2012: control device hw:1 Sat Nov 3 20:08:11 2012: control device hw:1 Sat Nov 3 20:08:11 2012: [1m [31mERROR: Failed to acquire device name : Audio1 error : Method "RequestRelease" with signature "i" on interface "org.freedesktop.ReserveDevice1" doesn't exist [0m Sat Nov 3 20:08:11 2012: [1m [31mERROR: Audio device hw:1 cannot be acquired... [0m Sat Nov 3 20:08:11 2012: [1m [31mERROR: Cannot initialize driver [0m Sat Nov 3 20:08:11 2012: [1m [31mERROR: JackServer::Open() failed with -1 [0m Sat Nov 3 20:08:11 2012: [1m [31mERROR: Failed to open server [0m If pulse is running but doesn't have the device then jack starts okay and the sink/source modules get loaded. So this is just a failure in negotiating the release. I'm told this is a problem with pulse's implementation of the interface. The only reference I can find is this: http://git.0pointer.de/?p=reserve.git;a=blob_plain;f=reserve.txt Can anyone provide any insight on this issue please? -- imalone http://ibmalone.blogspot.co.uk
