I have been adding audio to a video with Ardour on Ubuntu. At one point during the edit, I think I may have hit a wrong hotkey or something. The timeline got messed up and stretched into something much, much longer than the actual project. Then Ardour became unresponsive and I forced it to quit.
Now, when I try to open the Ardour session, it runs normally until I enter the editor. When I do, I have a few seconds to force-quit Ardour, or else my entire system will freeze and I have to do a hard reset.
I have the project file that’s causing the problem if anyone would like to see it.
Anyone have a clue how this is possible? Did I do something wrong? I’m new to Ubuntu and I’ve never had any serious problems using Ardour on Windows.
Edit:
Using i9 9900K 3.60 ghz processor
nVidia gtx 1080
Behringer UMC404HD USB audio interface
32 GB RAM
Ubuntu says it is up to date.
Ardour has a cryptic popup about some sort of memory limit.
Ubuntu is version 18.04.3 LTS
