audio routing is not saved

carlos_08

Hi, I'm running stage traxx on Mac, a few days ago all my audio routing was saved, I already had all the routing ready just by selecting my audio device in the sound settings. Today I made some changes, I changed the routing and it is no longer saved. I tried everything and it doesn't work.

That's a problem on MacOS Catalina I am not able to solve. Reason is that every time you start the app, macOS creates a new virtual device wrapping your audio interface and ST3 can only see this virtual device. As it is different on each start of the app, the saved routings are not restored.

Only solution is to update to Big Sur or newer where everything works as expected.

Please post a screenshot of your routing page after you edit it and then after restarting the app. And what happens when you change the audio interface in macOS settings while the routing page is openened?

I'm having this issue also with CADefaultDeviceAggregate with Catalina appending a different number each time the app is started. I can't update my OS to a later version, so a nice fix would be for Stage Traxx to use regex or similar to match with CADefaultDeviceAggregate and the channel number, which would get around the Catalina issue.

Is this a viable option to be implemented as other apps using Core Audio don't have this same issue in Catalina.

This issue only affects universal apps that are basically iOS apps recompiled for macOS. Native apps are not affected.

Interesting idea with the regular expression. I will take a look if this would be a viable option.

Brilliant, thanks Peter. Keep me updated either way! At the moment I'm having to virtual desktop into my Mac mini in the rack and set the devices each time when setting up for a gig.

I think that approach should work. When I replace the generic CADefaultDeviceAggregate device name with a custom generated device name based on the number of channels, the routing should be restored when ST3 is restarted. Of course it will not distinguish between different audio interfaces with the same channel count, but I think that's still better than what you have currently on Catalina.

I no longer have a Catalina test system so that I can not verify that it works as expected, but I will release this change in the next update 3.8.13. So please test it when 3.8.13 is released.
