Unable to control volume using MediaElement.Volume property
Comment
1 / 1
The MediaElement
class in WPF does not provide direct control over the volume of the audio playback. Instead, it relies on the audio device settings to control the volume.
To change the volume of the audio playback, you can modify the audio device settings using the MMDevice API
. Here's an example of how you can use it:
csharpusing NAudio.CoreAudioApi;
// ...
// Create a new MMDeviceEnumerator
var deviceEnumerator = new MMDeviceEnumerator();
// Get the default audio endpoint
var defaultDevice = deviceEnumerator.GetDefaultAudioEndpoint(DataFlow.Render, Role.Multimedia);
// Set the volume to 50%
defaultDevice.AudioEndpointVolume.MasterVolumeLevelScalar = 0.5f;
This code creates a new MMDeviceEnumerator
instance, gets the default audio endpoint, and then sets the volume to 50% using the MasterVolumeLevelScalar
property.
Note that this code requires the NAudio
NuGet package, which you can install using the following command:
mathematicaInstall-Package NAudio
