            Bug ID: 236779
           Summary: Video stutters and crackly sound on STP 140
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Mac (Apple Silicon)
                OS: macOS 12
            Status: NEW
          Severity: Normal
          Priority: P2

Hello,

I have noticed that with STP 140 that video elements stutter and sound crackles. I suspect this was happening before release 140, but I had assumed it was an issue with my Bluetooth headset rather than Safari. It was only today that I happened to notice the issue occur with the computer's speakers. I do not have this issue with blue Safari.

System Info:
macOS 12.2.1 (21D62)
MacBook Pro (16-inch, 2021) with Apple M1 Pro and 32 gigs of RAM.


Reproduction Steps:
1. In STP 140, go to https://www.w3.org/2010/05/video/mediaevents.html
2. Click "play()"

Expected:
Video plays smoothly and with clear sound.

Actual:
Video stutters and sound crackles.
