Audio Interface Reset after Quitting Ardour

This is resurrecting a bit a dead thread a bit, but i was having a similar issue. I noticed my files were all sped up after closing Ardour on my Kubuntu system. But i noticed it wasn’t just the audio file, it was every application after closing Ardour was sampled strangely, Firefox, VLC, Games, etc. A restart fixes it but i wanted a better way.

I tried reloading alsa, and a few other things locally but couldn’t find a fix to get it back to normal. So i decided to try a workaround. I loaded Ardour, started a new session, and set the sampling to 44.1 instead of my preferred 48 for projects. I Let the session load, and then closed Ardour. My computer was back to normal after that. So something curious about Ardour not setting the audio back to how it was before the session started. Unless I hear a better fix, i may just keep doing that.

Run my sessions in whatever sample i need and then when i’m done, restart Ardour one last time, and set the sampling to the usual standard 44.1 to straight it out for everything else.

Which desktop audio server are you using, PulseAudio or PipeWire, and which version?
I would expect the audio server to set the interface parameters as desired after Ardour releases control and the audio server takes control again.

‘pactl info’ shows pulseaudio v15.99.1

I will have to let someone else comment on whether that problem is known for that version, my distribution switched to Pipewire before that version of PulseAudio was released so I don’t have a comparison.

No worries, I’ll tinker about and I still need to upgrade to Ubuntu 24 so things might even be fixed once I do.
