I have no way to explain the issues you have identified. In between times, did you boot another O/S?
I had (of course ... the other OS is my usual), though the sound module was playing other things OK. Having repowered the module Focusrite 2i2 v1), one would have expected any left-over OS-related stuff would be well gone. I do get a warning message:
Windows Audio Session error: Input and output sample rates must match. Audio input (recording) will be disabled. The error number is -9997 [2024.1111.0, 22/08/2024 12:21:28]
which might be relevant, though I think everything is 44.1k. I'm
rendering to 48k as this is for video.
On very rare occasions I have had similar problems. I determined it was a bad file. Fortunately I had a backup and it played fine. YMMV
Hmm, I guess that could be. Maybe I should have just tried another file first. I binned the work in progress anyway as I'd lost the style and at least one RT. It was quicker to just start over than try to restore the broken bits.
I noticed another oddity, too, whilst doing this. I think this is the first time I've tried to set the music duration to exactly match the video. I was using the time on BiaB's title bar, but thought to check the
actual duration before I sent the file, only to discover that it was about 3s longer. I guess that BiaB does not count its self-generated ending in the time. Ho Hum, live and learn ... cut out some more bars and tweak the tempo again.....
Edit: Oh crikey ... and another oddity: Alt-F5 rest all-excluding is not-resting the wrong guitar of the two.
It sometimes feels like every time I touch BiaB I expose a bunch of weird issues.
Sigh! Ah, OK, ... frozen tracks! PICNIC.
