Mid 2012 MBP issue

Upgraded my mid 2012 MacBook pro to Sonoma thanks to the incredible team doing this. At first everything worked perfectly and I couldn't be happier. I use this laptop as my DND laptop where I do music and maps on a friend's apple tv via airplay. Just this last week suddenly video works but audio doesn't. Audio will only play on my laptop which is absolutely bizarre as nothing has changed. If I try to select the apple tv as the audio receiver in audio options it just spins for eternity. Any ideas?
