Expected result

The androidx.media3 library should not cause a crash due to invalid state.

Actual result

The check in onAudioCapabilitiesChanged() fails because it is not called from the main thread. This appears to be a regression introduced in 432cde60511db47a739973cff7c2da287380fa15, to be specific the newly introduced "OnRoutingChangedListenerApi24".
