I also found some information about "IAudioEndpointVolume Interface", but don't know how to start from here: http://msdn.microsoft.com/en-us/library/dd370892(v=vs.85).aspx

Could not find any VB6 information about it.

Hi Guys,

Found the solution on: http://caudioendpointvolume.codeplex.com/

Attached the complete file I made.

Enjoy

Glad to hear it Kitter. No need to bump your VBF topic then.

I don't answer programming questions via PMs. That's what the forum is for! 

I've just tried your Vista_Win7_Master_Volume.rar on my Vista 32bit. I had Windows Media Player playing a mid file and Devices, Windows Sounds and Windows Media Player showed in the Volume Mixer but the app didn't as it does in yours.

If you step down the Master Volume Scaler button all 3 sliders drop but the Windows Media Player volume control doesn't. If you drag the Windows Media Player in Volume Mixer it drags the Windows Media Player volume control.

Oh I forgot to mension always use Option Explicit in all Forms, Modules, Class Modules and UserControls. If you don't know what it does or how to set it up just ask?

Hi Kiter,

Very good job! I inspired to make programs with call COM model in VB and VBA, but I have two asks:

1. Is the way to use this in VB.NET?

2. I need call IWMDeviceManager2::Reinitialize method, but I don't find CLSID for WMDeviceManager2 to create IWMDeviceManager2 {923E5249-8731-4C5B-9B1C-B8B60B6E46AF} interface with coCreateInstance. I am afraid it’s necessary to use IComponentAuthenticate and SetCertificate method… Note: I don’t have C# compiler

Now I have problem with HDMI Audio in Windows 8. After sign in it works fine. After switch off TV audio output automatically change to wireless headphones in rear jack - very nice future! But after switch on TV HDMI connector stay’s “unplugged”. I need to disconnect a reconnect HDMI cable or sign out and resign in to Windows. I think this method is solution for my problem - see http://msdn.microsoft.com/en-us/library/windows/desktop/ff801386(v=vs.85).aspx.

Note: I make VB program, which switch audio outputs by pressing Mute button e.g. on Remote Controller (I uploaded it).

I'm wondering if CLSID for MediaDevMgr will work?

CLSID_MediaDevMgr,0x25BAAD81,0x3560,0x11D3,0x84,0x71,0x00,0xC0,0x4F,0x79,0xDB,0xC0);
