Sound noise while video function enabled with M1 Macbook.

Spec: M1 macbook Air (RAM 8gb / SSD 512gb) Version: 6.5.1 Hello, I am using M1 macbook Air for Rekordbox DJ. with 6.5.1 update, I understand rekordbox has been compatible for M1. However, if quality setting for Video funtion is High, there is sound noise for the music playing. (With middle option, it is okay.) It only happens when two video tracks are playing simultaneously. I am just wonder if it would be fixed future update, or is there any way to resolve this issue.
