[+] [1740] Android 17 AIMP loses audio focus when opened by external command

[defkev]

e.g. by connecting my AirPods Pro:

* AIMP will start as per usual but go quiet almost immediately unless brought to the foreground
* The widget will ironically still show as playing
* I assume because it still does, you just can't hear it

This can be reproduced reliable by opening another app (AIMP losing focus) or locking the device.

I already tried disabling battery saver (Unrestricted), disable CarPC, and enabling Ignore external commands.

The only reliable workaround I found so far is by opening AIMP manually.

I assume this has something to do with hardened background audio (https://developer.android.com/about/versions/17/changes/bg-audio) introduced in 17 since AIMP doesn't spawn a foreground service?

Refer to the "About" dialog of the app, and check the "enable logging" option. Restart the app. Now, reproduce an issue and send the log file to me. Please, report to me a approximate time when issue was happened.

Man sorry I completely forgot about this after leaving town.

This is indeed caused by AudioHardening introduced in Android 17:

And can be disabled using:

Code: [Select]

cmd audio set-hardening 0
in adb

Its a runtime setting so resets on reboot.
I currently have it in Tasker to run on boot-complete since this seems to affect more apps including YouTube Premium.

Cheers

Ok. thanks for a workaround
