What I've found, is that through my wired headphones I don't get stuttered audio in Orion 0.99.112-beta. However, when the output is set to my MacBook's speakers or the Thunderbolt Display speakers, the audio stutters. When outputted to AirPods Pro, the audio stutters and then just goes silent after about a second.
Also, if I change the audio output while watching a YouTube video, the video will pause and put up the busy/loading/buffering animation over the video and will not be able to be played again until I refresh the page.
