iOS: By default the audio only works through an earpiece, not the main speaker

OS: iOS
Device: iPhone 12

Hi, I have a bug that I can't quite resolve at first glance. For some reason, the iOS SDK defaults to using the earpiece audio instead of the main speakers. When I connect a second source, like Bluetooth earbuds, it works correctly. I can switch between the main speaker and the earbuds with no issues (but still no earpiece in the sources).

Here is how my room is configured:

room = VideoSDK.createRoom(
      defaultCameraIndex: 1,
      roomId: widget.meetingId,
      token: widget.token,
      displayName: 'Customer',
      micEnabled: micEnabled,
      camEnabled: webcamEnabled,
      maxResolution: 'hd',
      notification: const NotificationInfo(
        title: "Video SDK",
        message: "Video SDK is sharing screen in the meeting",
        icon: "notification_share",
      ),
    );

When nothing is connected to the phone, getAudioOutputDevices returns only 1 audio device with "Speaker" deviceId. The sound comes through the earpiece:

I was able to fix this by setting the room's multiStream parameter to false.
