[expo-camera][IOS] Mute is not working when switching from picture to video

Minimal reproducible example

What platform(s) does this occur on?

IOS

Did you reproduce this issue in a development build?

Yes

Summary

My app use case is the ability to "switch" from photo to video by long pressing the capture button. When switching from picture to video mode, the video output is always muted.

Related to this: #27984

Possible solution is to explicitly set muted={!isRecording}. However, the "dead frame" is clearly visible when doing so which is now a performance issue.

Note: no issue when mode is always set to video.
