Hi,
I know there are threads with similar topics, but all claim to have been solved and I see this with current git master, so …
I tested ardour 7 on linux with a notebook and on a server. Everything is fine, until I want to quit the application. Then it just hangs until I kill it (with a TERM signal or similar).
I run on Opensuse Tumbleweed with latest updates.
My glibc is version 2.37 (another thread mentions the hanging exit is fixed with 2.36)
I tested ardour 7.3 coming with the distro, your downloadable demo and a selfcompiled version from git (master as of today). All have the same problem.
What might be different than most other installations is that I use pipewire (with pulseaudio and jack compatibility enabled) as audio backend.
To test it I just start ardour, without plugins, new empty session, then immediately close.
I am asked about saving/discarding the session (my answer doesn’t matter). Then it hangs.
These are the backtraces of all threads while it hangs, maybe you can do something with it:
