Sound can't go to 0 (muted) on iOS and Android

[Spharian]

Describe the bug

When changing volume on a device, the volume can't go to 0 (tested on iOS and Android). It feels like a "minimum volume" is set somewhere.

To Reproduce

1. Use the VideoView component:

   <VideoView
   style={{
   flex: 1,
   backgroundColor: Colors.black,
   }}
   objectFit="cover"
   videoTrack={streamerParticipant.getTrackPublication(Track.Source.Camera)?.videoTrack}
   />

2. Try to reduce the volume to the minimum on iOS or Android, the sound is never muted (volume to 0) as it should be.

Expected behavior

The volume should go to 0 and we shouldn't hear the remote participant.

Solved by configuring AudioType.MediaAudioType(): https://github.com/livekit/client-sdk-react-native?tab=readme-ov-file#kotlin Using Expo, this is forcing me to keep an android folder and not having it in the .gitignore then Expo take in into account for builds.

Thanks for the update @Spharian, it's on our roadmap to make Expo integration a lot easier! @davidliu
