All audio comes out of the earpiece instead when notifications are used

# Bug Report

## Problem

When I use javascript code from this package, all the audio including music in the WKWebView outputs audio through the earpiece. The volume is really low. I tried setting all audio to come out of the main speaker using this audio plugin, but the notification beeps no longer are outputted.
