No audio in when correct input is selected

Technical Support

I currently can’t find a way to record audio in the software.
After selecting JACK as the audio backend, I can see the correct audio devices. Upon adding an audio track, selecting the correct inputs, and priming the track to record, I do not see any waveform when recording. Playing back the recorded sample, it is clear that there is no audio.

When using a patchbay, I can see that the correct audio channels are linked.

When using other applications, like tenacity, I can record the channels from my audio interface just fine (I made sure it was using jack).

I also noticed that the tracks do not save the ‘input’. Upon restarting the application, they are set to the default ‘No left / right input’.

After looking at the terminal output I see nothing of note, but I do not know what I am looking for really.

Please let me know if I am doing something wrong!
I really enjoy the ui, and ease of use while also having tons of functionality!

Thank you.

After a few days of trying to figure it out using random different settings I got it to work for one session. Unfortunately any other attempts have failed. As soon as I restarted the program, the audio no longer recorded.
Unsure of what exactly I did different this time.

I have spent more hours on this than I’d like to admit.
Can’t figure it out.

Any help would be appreciated.

Thank you.

I’m also experiencing this issue.

I am using the stable Flatpak on Bluefin OS (based on Fedora), with the Focusrite Scarlett Solo 4th Gen audio interface and JACK (pipewire) backend. It does work occasionally, but it is random and rare.
