CometChat Calls SDK v5 — Audio Mode (React Native)

Overview

Switch the audio output between speaker, earpiece, Bluetooth, and headphones during an active call. This is a mobile-specific feature not available on the web SDK.

Key Imports

import { CometChatCalls } from '@cometchat/calls-sdk-react-native';

Implementation

Set Audio Mode

CometChatCalls.setAudioMode('SPEAKER');     // route to loudspeaker
CometChatCalls.setAudioMode('EARPIECE');    // route to earpiece
CometChatCalls.setAudioMode('BLUETOOTH');   // route to connected Bluetooth device
CometChatCalls.setAudioMode('HEADPHONES');  // route to wired headphones

Listen for Audio Mode Changes

CometChatCalls.addEventListener('onAudioModeChanged', (mode) => {
  // mode: 'SPEAKER' | 'EARPIECE' | 'BLUETOOTH' | 'HEADPHONES'
  console.log('Audio mode changed to:', mode);
});

Set Default Audio Mode (Before Joining)

<CometChatCalls.Component
  callToken={callToken}
  sessionSettings={{
    audioMode: 'SPEAKER',         // default audio output
    hideAudioModeButton: false,   // show the audio mode button
  }}
/>

Custom Audio Mode Picker Example

import React, { useState, useEffect } from 'react';
import { View, TouchableOpacity, Text, StyleSheet } from 'react-native';
import { CometChatCalls } from '@cometchat/calls-sdk-react-native';

type AudioMode = 'SPEAKER' | 'EARPIECE' | 'BLUETOOTH' | 'HEADPHONES';

function AudioModePicker() {
  const [currentMode, setCurrentMode] = useState<AudioMode>('SPEAKER');

  useEffect(() => {
    const unsub = CometChatCalls.addEventListener('onAudioModeChanged', (mode) => {
      setCurrentMode(mode);
    });
    return () => unsub();
  }, []);

  const modes: { mode: AudioMode; label: string }[] = [
    { mode: 'SPEAKER', label: '🔊 Speaker' },
    { mode: 'EARPIECE', :  },
    { : , :  },
    { : , :  },
  ];

   (
    
  );
}

 styles = .({
  : { : , :  },
  : { : , : , :  },
  : { :  },
  : { : , :  },
});

Constants

CometChatCalls.AUDIO_MODE.SPEAKER     // 'SPEAKER'
CometChatCalls.AUDIO_MODE.EARPIECE    // 'EARPIECE'
CometChatCalls.AUDIO_MODE.BLUETOOTH   // 'BLUETOOTH'
CometChatCalls.AUDIO_MODE.HEADPHONES  // 'HEADPHONES'

Gotchas

• setAudioMode() only works during an active session
• Bluetooth mode only works if a Bluetooth audio device is connected — otherwise it may fall back to speaker
• Headphones mode only works if wired headphones are plugged in
• The onAudioModeChanged event fires when the mode changes for any reason (user action, device connected/disconnected)
• For voice calls, the default is typically EARPIECE; for video calls, it's SPEAKER
• hideAudioModeButton: true hides the built-in audio mode button — use this when providing your own picker
• This feature is not available on the web SDK — it's mobile-only
• On Android, ensure BLUETOOTH and BLUETOOTH_CONNECT permissions are in your manifest
