Hi again,
I can’t find the post now, but I tried everything you suggested someone else with at similar problem:
Adjusting bit-rate, real time conversion, audio to buffer separately and together - no effect.
They were not multi track recordings and there is no difference whether the recording starts at zero or not.
I don’t think it is a Yosemite problem. When I finally tried the 2.0.3 I was following this thread:
https://forum.audacityteam.org/t/downgraded-back-to-2-0-3-because-playback-on-2-0-5-crackles/32771/1
And he doesn’t use Yosemite as far as I can tell. (I am on a Mac Mini FYI).
I have a few other problems in Yosemite: I can’t use some of the plug ins (on the lower half of the menu in Effects) and it crashes after I finish one project, save and start at new one. I think other people have given that report too. (I have learned the hard way before and somehow managed to forget and do it again: I shouldn’t have updated to Yosemite. Duh!)
Thanks,
Grete
