How do I change the default playout device on Mac Native WebRTC?

To change the default playout device on Mac Native WebRTC, you can use the WebRTC APIs provided by the browser. Here's an example of how you can achieve this using JavaScript:
javascript// Check if WebRTC is supported by the browser
if (navigator.mediaDevices && navigator.mediaDevices.getUserMedia) {
// Get the current media stream
navigator.mediaDevices.getUserMedia({ audio: true, video: false })
.then(function(stream) {
// Get the list of available audio output devices
return navigator.mediaDevices.enumerateDevices()
.then(function(devices) {
// Find the desired audio output device
var desiredDevice = devices.find(function(device) {
return device.kind === 'audiooutput' && device.label === 'Your Device Name';
});
// Set the desired audio output device as the default
if (desiredDevice) {
var audioTrack = stream.getAudioTracks()[0];
var audioOutputConstraints = { deviceId: { exact: desiredDevice.deviceId } };
return navigator.mediaDevices.getUserMedia({ audio: audioOutputConstraints })
.then(function(newStream) {
// Replace the existing audio track with the new audio track
stream.removeTrack(audioTrack);
newStream.getAudioTracks().forEach(function(newTrack) {
stream.addTrack(newTrack);
});
});
}
});
})
.catch(function(error) {
console.error('Error accessing media devices:', error);
});
}
In this example:
- The
getUserMedia
method is used to obtain the current media stream with audio enabled. - The
enumerateDevices
method is called to retrieve the list of available media devices, including audio output devices. - The desired audio output device is identified based on its
label
. Modify thelabel
check to match the desired device name. - If the desired audio output device is found, a new media stream is obtained using the
getUserMedia
method with thedeviceId
constraint set to the ID of the desired audio output device. - The existing audio track from the original media stream is replaced with the new audio track from the new media stream, effectively changing the default playout device.
Note that this example uses the standard WebRTC APIs, which may have limited support in older versions of certain browsers. It's important to test and ensure compatibility with the target browser versions and consider using any necessary vendor-specific APIs or libraries to achieve the desired functionality.
