Glitchy audio on raspberry pi 4

[narFnarF]

I installed RPiPlay on a fresh install of Raspbian. When I mirror from my iphone to the RPiPlay and watch a video, the visual plays smoothly, but the audio is super choppy.

Using:

• Raspberry Pi 4B
• iPhone 6s (ios 14)

I tried both analog audio and hdmi audio. Both are glitchy. Or sometimes, after a few disconnect/reconnect, audio stops completely.

Note: Shairport-sync works perfectly on the same device (audio plays without glitch)
