I recently upgraded to Ardour 7 and decided to record an idea before I forget it.
created a new session, with ALSA, 48KHz, 128samples, 2 periods (default)
set bpm 60
enabled clicktrack
recorded a stereo track [synth]
created a midi track [RedZeppelin drums] and sketched some pattern
recorded a stereo track [guitar]
Now:
UI is lagging during playback (I had this from time to time on 6.9)
track go more and more out of sync during playback (more or less okay first two bars, by the end of the 15th bar barely listenable) - no, I don not have perfect sense of time but never ever experienced this
System: Dell Precision 5750 laptop, 6-core i5-11500H @ 2.90GHz, Ubuntu Studio 22.04LTS, 5.15.0-52-lowlatency #58-Ubuntu SMP PREEMPT, SSD, M-Audio Air 192|14, Ardour7.0.0 (built using 7.0 and GCC version 6.3.0 20170516) official build.
Is that anything I’m doing wrong, have misconfigured, or just bumped into a bug with new time implementation?
Any chance you got a large value entered into the hardware input latency and hardware output latency fields that is causing Ardour to make excessive latency compensation?
