P.S.: The system sounds are hearable through the headphones - before and after rebooting.

Strange issue. As I said, it's not readily reproducible on the Android devices I have available, including some Samsungs, albeit different models. No similar reports from others either so far.

Let me know if the device reset changes anything.

Dear Dave,

a complete device reset did not do the trick. Still the same issue.

I additionally made this observation: when I adjust the volume during playback within the Inquisit 7 app on my Samsung tablet using headphones, the tablet changes the "system" volume instead of the "media" volume. However, if I run the same test without headphones connected, the volume buttons correctly adjust the "media" volume during playback. Could it be that Inquisit 7's audio via Samsung tablet is not routed through the standard media channel when headphones are connected?

Best,

pinguin

Inquisit uses the media channel, but for some reason the media channel doesn't appear to be routed through the wired headphones on those tablets, but remains routed through the speakers.
Android 12 introduced some major changes to audio routing, but the app in principle supports and adheres to those specifications. It's possible this comes down to some custom stuff Samsung did in that Android 12 distro that breaks the expected behavior. Conferring with our lead Android dev about this and see if we can find a device where this is reproducible and whether we can deploy a workaround. I will update this thread once I know more.

Thank you - this would be much appreciated!

If by any chance we will find a solution ourselves, we will also get back to you here.

Hi Dave,

a tiny update: when we use USB-C to 3.5mm jack adapters, the sound will be output through the headphones.

Maybe this information is important to know for the developers.
