I am on Pop!_OS 22.04 LTS, running Ardour rev 6.9.0~ds0-1build1 usually with Jack on 1024 Samples.
I finished editing my Podcast earlier today, shut off my PC and did some stuff. When I came back, started it up again and wanted to export the Podcast I noticed that the file Ardour produced was completely silent.
So I looked around a few things, changed the audio systems to pulse and alsa to see what happens. with logging out and back in between all changes.
Any other project I made still works, plays and exports fine. I even compared the preferences window tab for tab and it is the same.
There are no error messages appearing in that project in the ardour log, the volume bars for the individual tracks move, the master one does not move and the volume bars on the top right also do not move. whatever I choose the DSP indicator always sits at 0%
Please help, what did I do wrong?
