See the update in the first post. I think this is what you need.
there’s something wrong with sound jamming… at first, the volume really goes down, but then there is a pause…
as a result, any player goes on pause : (
this may be due to the fact that the voice is played in the alarm channel and the system automatically podruzamevaetsya that everything that plays should pause… I have no other suggestions.
the idea is amazing. this is a very necessary extension for today, but unfortunately it does not work properly yet. I really believe and expect that everything will work out.
It’s strange. It works fine on my phone: the sound is muffled and plays in parallel with the voice, like a background sound. After, the sound volume is restored to the previous level. Apparently it works differently on different phones.
