AirPlay problems

Hi.
After updating my iPhone 8 to ios 14.6 b3, my airplay is not working correctly.
It cuts the sound after a millisecond of listening. I’ve never experienced this before updating, and it drives me nuts.
Its not a problem streaming from my other devices with a previous firmware, so i’ve narrowed it down to being an issue with this beta.
Is anyone else experiencing this problem?

Thank you
