I’m having the same issue, except after a few seconds, the audio just cuts out completely.
I tested this with both bluetooth headphones and wired headphones and the issue was definitely worse with bluetooth.
I also tested with different video resolutions and playback speeds on YouTube (I assumed maybe my system was just slow?) and playing the video at 1x speed at the lowest resolution had minimal effect on the stuttering issue compared to playing the video at 2x speed in 1080p.
I’m using Orion v0.999.112 on MacOS v12.2 (21D49) if that helps narrow down the issue any.
Also forgot to mention that I tested it with Compatibility mode enabled and was still consistently having the audio stuttering issue.
