            Bug ID: 275726
           Summary: [regression]audio sounds like a robot on Mac OS(higher
                    than 14.5)
           Product: WebKit
           Version: Safari 17
          Hardware: Mac (Apple Silicon)
                OS: macOS 14
            Status: NEW
          Severity: Critical
          Priority: P2
         Component: Media

Audio sounds like a robot after changing the system's default speaker.

you can visit https://loquacious-kulfi-549dee.netlify.app and click start. You can hear your voice from your default speaker normally.

But the sound becomes distorted if you change your system's default speaker now.

I can reproduce it on Safari Version 17.5 (19618.2.12.11.6)/Safari Technology PreviewRelease 196 (Safari 17.4, WebKit 19619.1.16.3)/Safari Version 18.0(20619.1.15.11.1).

Audio is always OK on Version 17.4.1 (19618.1.15.11.14), I think it's a critical regression.

The demo is very simple, getUserMedia -> audioContext.AudioNode -> audioContext.workletNode -> audioContext.destination. You can see details on the demo site.
