Enabling recording devices programmatically
Enabling recording devices programmatically
I want to enable the disabled device in Sound - Recording devices list programmatically
I was able to get a list of disabled devices using Naudio
But there is no way to enable it using Naudio.
so I tried also using IMMDevice interface but I couldn't find out how to do this.
I tried also Registry Edit
//Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\{87bd5990-b012-41f1-83f7-f267ed7780a7}
RegistryKey root = Registry.LocalMachine.OpenSubKey("SOFTWARE", true).OpenSubKey("Microsoft", true).OpenSubKey("Windows", true).OpenSubKey("CurrentVersion", true).OpenSubKey("MMDevices", true).OpenSubKey("Audio", true).OpenSubKey("Render", true).OpenSubKey("{87bd5990-b012-41f1-83f7-f267ed7780a7}", true); //{87bd5990-b012-41f1-83f7-f267ed7780a7} any Playback Device ID
MessageBox.Show($"Value Before {root.GetValue("DeviceState")} { root.GetValueKind("DeviceState")}");
root.SetValue("DeviceState", 0x10000001, RegistryValueKind.DWord);
MessageBox.Show($"Value After {root.GetValue("DeviceState")} { root.GetValueKind("DeviceState")}");
or
Registry.SetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\{87bd5990-b012-41f1-83f7-f267ed7780a7}", "DeviceState", 0x10000001, RegistryValueKind.DWord);
but this will need Administrator Rights and I want it to work for any user.
Solution
I found this solution and I am not sure if there is any other solution :
Using NAudio and TestStack.White you can open the Sounds List and enable and close it this will not need for admin privileges:
using NAudio.CoreAudioApi;
using System;
using System.Diagnostics;
using System.Linq;
using System.Runtime.InteropServices;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace Enable_Device
{
class Program
{
[DllImport("User32.dll")]
public static extern Int32 FindWindow(String lpClassName, String lpWindowName);
[DllImport("user32.dll", SetLastError = true)]

[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam);
private const UInt32 WM_CLOSE = 0x0010;

string driverName = "Stereo Mix"; // any device name you want to enable
MMDevice mMDevice;
using (var enumerator = new NAudio.CoreAudioApi.MMDeviceEnumerator())
{
mMDevice = enumerator.EnumerateAudioEndPoints(DataFlow.Capture, DeviceState.Disabled).ToList().Where(d => d.FriendlyName.ToLower().Contains(driverName.ToLower())).FirstOrDefault();
}
if (mMDevice != null)
{
driverName = mMDevice.FriendlyName;
int charLocation = driverName.IndexOf("(", StringComparison.Ordinal);
if (charLocation > 0)
{
driverName = driverName.Substring(0, charLocation);
driverName = driverName.Trim();
}
}
else
{
MessageBox.Show($"{driverName} Coudn't Found as Disabled Device.");
return;
}
TryEnable(driverName, mMDevice);
}
private static void TryEnable(string driverName, MMDevice mMDevice)
{
try
{
var hwnd = 0;
hwnd = FindWindow(null, "Sound");
Process soundProc;
if (hwnd == 0)
{
soundProc = Process.Start("control.exe", "mmsys.cpl,,1");
}
else
{
CloseWindow((IntPtr)hwnd);
while (hwnd == 0)
{
Debug.WriteLine($"Waiting to Close ...");
hwnd = FindWindow(null, "Sound");

var id = GetWindowThreadProcessId((IntPtr)hwnd, out uint i);
TestStack.White.Application application = TestStack.White.Application.Attach((int)i);
Debug.WriteLine($"{application.Name}");
TestStack.White.UIItems.WindowItems.Window window = application.GetWindow("Sound");
var exists = window.Exists(TestStack.White.UIItems.Finders.SearchCriteria.ByText(driverName));
if (exists)
{
TestStack.White.UIItems.ListBoxItems.ListItem listItem = window.Get<TestStack.White.UIItems.ListBoxItems.ListItem>(TestStack.White.UIItems.Finders.SearchCriteria.ByText(driverName));
listItem.Focus();
window.Keyboard.PressSpecialKey(TestStack.White.WindowsAPI.KeyboardInput.SpecialKeys.UP);

}
if (mMDevice != null)
{
if (mMDevice.State == DeviceState.Active)

Debug.WriteLine($"{ mMDevice.FriendlyName}");
CloseWindow((IntPtr)hwnd);

catch (Exception)

}
If you have Admin privileges
private void EnableAsAdmin()
{
string driverName = "Stereo Mix";
string deviceId = "";
MMDevice mMDevice;
using (var enumerator = new NAudio.CoreAudioApi.MMDeviceEnumerator())
{
mMDevice = enumerator.EnumerateAudioEndPoints(DataFlow.Capture, DeviceState.Disabled).ToList().Where(d => d.FriendlyName.ToLower().Contains(driverName.ToLower())).FirstOrDefault();
}
if (mMDevice != null)
{
driverName = mMDevice.FriendlyName;
int charLocation = driverName.IndexOf("(", StringComparison.Ordinal);
if (charLocation > 0)
{
driverName = driverName.Substring(0, charLocation);
driverName = driverName.Trim();
}
deviceId = mMDevice.ID;
charLocation = deviceId.IndexOf(".{", StringComparison.Ordinal);
if (charLocation > 0)
{
deviceId = deviceId.Substring(charLocation + 1);
deviceId = deviceId.Trim();
}
if (!string.IsNullOrWhiteSpace(deviceId) && AdminHelper.IsRunAsAdmin())
{
if (Environment.Is64BitOperatingSystem)
{
RegistryKey localKey =
RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.LocalMachine,
RegistryView.Registry64);
localKey = localKey.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Capture\" + deviceId, RegistryKeyPermissionCheck.ReadWriteSubTree, RegistryRights.SetValue);
localKey.SetValue("DeviceState", 1, RegistryValueKind.DWord);
}
else
{
RegistryKey localKey32 =
RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.LocalMachine,
RegistryView.Registry32);
localKey32 = localKey32.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Capture\" + deviceId, RegistryKeyPermissionCheck.ReadWriteSubTree, RegistryRights.SetValue);
localKey32.SetValue("DeviceState", 1, RegistryValueKind.DWord);
}
}
if (mMDevice != null)
{
if (mMDevice.State == DeviceState.Active)
{
App.Current.Dispatcher.Invoke(() =>
{
MessageBox.Show($"{driverName} Enabled ");
});
}
}
}
else
{
App.Current.Dispatcher.Invoke(() =>
{
MessageBox.Show($"{driverName} Coudn't Found as Disabled Device.");
});
return;
}
}
