How to route audio to phone speakers when a2dp profile is connected in android for app?

Question

Android

However, hello! I have an android smartphone that is permanently connected to the car. At the same time, when connected via bluetooth to the radio and an active a2dp profile, all sound is transmitted through the car's speakers. When you change the sound source, for example, on the radio, all sound notifications from the phone disappear (in this case, the work of the Yandex navigator is of interest). When a2dp is deactivated, the sound of the navigator goes through the phone's speakers, but the ability to select the phone as an audio source for the radio disappears. Perhaps someone knows software or some other way that allows you to wrap the sound of a specific application forcibly into the required audio channel so that you do not have to go into the settings and turn a2dp on and off every time?

Write to the developers of Yandex.navigator - this is the surest way to solve your problem.
