Ardour 2.3 on Ubuntu Hardy - 100% cpu
The upgrade to Ubuntu Hardy and thus to Ardour 2.3 seems to have broken my system. Simply put: I open an Ardour session and the CPU use jumps to 100% and stays there. It takes something like ten seconds for the program to register when I try to select a different sound file. It will play a session fine, but doing any real editing (let alone trying to run a sequencer at the same time!) causes overload, crashes etc. It doesn't seem to be anything to do with the plugins - disable or enable, it's still 100% CPU. The really weird thing is that the programme doesn't want to close down! It ignores a "Quit" command from the menu - I can "Close" the session and then quit from the next window but - here's the surprise - check System Monitor and the Ardour session is STILL running, consuming 50% of CPU.
Hardware specs: Celeron 2GHz processor, 768M RAM, running kernel 2.6.24-16-rt.
Any suggestions? I can't see this anywhere as an already-noted bug.
