Webbrowser disable all audio output - from online radio to youtube
browser, c#, wpf
Solution
Here is how you can do it with ease. Not specific to WebBrowser though, but does what you requested: I just want from my application 100% mute, no sounds at all.
using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;
namespace WinformsWB
{
public partial class Form1 : Form
{
[DllImport("winmm.dll")]
public static extern int waveOutGetVolume(IntPtr h, out uint dwVolume);
[DllImport("winmm.dll")]
public static extern int waveOutSetVolume(IntPtr h, uint dwVolume);
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
// save the current volume
uint _savedVolume;
waveOutGetVolume(IntPtr.Zero, out _savedVolume);
this.FormClosing += delegate
{
// restore the volume upon exit
waveOutSetVolume(IntPtr.Zero, _savedVolume);
};
// mute
waveOutSetVolume(IntPtr.Zero, 0);
this.webBrowser1.Navigate("http://youtube.com");
}
}
}
Problem
My webbrowser: XAML: ``` //... xmlns:my="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration" //... <my:WindowsFormsHost Name="windowsFormsHost"/> ``` Code behind C#: ``` System.Windows.Forms.WebBrowser Browser = new System.Windows.Forms.WebBrowser(); windowsFormsHost.Child = Browser; ``` My question is how to disable all audio output. I found this: C#: ``` private const int Feature = 21; //FEATURE_DISABLE_NAVIGATION_SOUNDS private const int SetFeatureOnProcess = 0x00000002; [DllImport("urlmon.dll")] [PreserveSig] [return: MarshalAs(UnmanagedType.Error)] static extern int CoInternetSetFeatureEnabled(int featureEntry, [MarshalAs(UnmanagedType.U4)] int dwFlags, bool fEnable); ``` Its fine, but this code disable only "click" sound, so its kind of useless in this case. I just want from my application 100% mute, no sounds at all. I've read that in this webbrowser it need to be done through Windows Sounds, but I cant really bielieve that I cant do this in code.
