I have a Pixel 5 (Android 11) and I want text/SMS notifications to play on BOTH a connected bluetooth AND phone speaker. I my bluetooth earbuds are not always in my ear, although they may be paired turned on, and I miss important text message notifications. Interestingly, incoming call ringtones DO play on both the headset and phone speaker.
I've heard this behavior is "normal" in how audio channels are processed but it is, in my scenario, quite problematic.
As a possible starter to the solution, does anyone know if a Tasker routine could be created to "duplicate" the notification received in one channel (bluetooth) to another channel (phone speaker) if the bluetooth device is connected?
