how to control windows 7 master volume. I would like to get the current volume / set the volume and also mute / unmute it.I've found lots of examples of pre vista volume control but only a single c# which is no good to me beings a major newbie with vb.net (I've play with vb6 before now)As far as I can see I need to do something with DefaultAudioEndpoint.. but what I'm not sure. I'm building a media player which is why I'm after controlling the master as well as my application.
I am trying to make an application that is able to turn master volume on and off (Mute unmute). And what I have done so far is increasing and decreasing volume, but if sound is turned on mute then it wont start anyway. And that was really a lot of code to do that, so is there an easy way to mute sound or is it equally alot to do.
I have tried SendKeys.Send(Keys.VolumeMute) But with no effect, and I have tried using chr(173) instead of keys.volumemute. (I have a variable that looks if the sound was mute or not from start so it can be default afterwards).
Is there any way to adjust master audio volume directly using .net?
I can find C++ coding which, sadly means nothing to me. There's also quite a lot out there for VB4, 5 and 6 but I can't get any of that to relate to .net. Most of those seem to want to invoke the 'Slider' via the mouse which is not what I'm after.
I would like to be able to: -
Record the current Audio Volume setting, Change it (up or down), Play a *.wav file, then Return it to it's original level.
I've had some success with 'AxWindowsMediaPlayer' but only with it's own increase / decrease functions. I can only get it to increase the volume as far as the main system volume is set, so if that's at zero I get no output at all. As for part one of my requirement, record the current level, I've got nowhere with that at all. I tried putting the one file I want to use in resources but can't find how to access it, I have had to put the file in a folder and call it from there, it works but it seems a little crude.

It seems like this would be a very easy thing to accomplish, but, from what I can tell, it's most definitely not. My OS is Windows 7. All I need to do is get the current volume/audio level - the master volume. When you click the little speaker icon in the task bar and change the volume - I need that number. All I need to do is get the current volume and assign it to a label. So if the volume is at 74 when the application starts, I need my label to display 74. I've been searching for days now for a way to do this and I'm starting to get frustrated. I've looked everywhere. I've tried 3 different classes, at least a dozen different codes, assorted imported dll's- none of it even came close to what I need. From what I can tell, the current methods are all designed for windows xp. I need a way to do it in windows 7.
I'm attempting to use waveOutSetVolume from coredll.dll to gradually increase the audio volume from silent (or near silent) to maximum.
Most of the code examples I'm finding show some predefined set points for Off, Low, Normal, Medium, High, and Very High like this:
Public Enum Volumes As Integer OFF = 0 LOW = 858993459
[Code]....
OK, and here's some API documentation which doesn't make a lot of sense to me in this particular context. What is low-order word and high-order word and how can they both exist in a single value?
· dwVolume New volume setting. The low-order word contains the left-channel volume setting, and the high-order word contains the right-channel setting. A value of 0xFFFF represents full volume, and a value of 0x0000 is silence. If a device does not support both left and right volume control, the low-order word of dwVolume specifies the volume level, and the high-order word is ignored.
How do I change the Windows Speaker Volume (The Main Output Volume Control Volume Value) via VB.NET? I want a way to like indirectly change the whole system's volume like we do it from the Volume Control application on Windows 7
Maby ive been going about this the wrong way. Im attempting to change the system volume using VB.net. I dont want to use the mediaplayer stuff because i dont want that to be open the whole time. if someone could point me to a working API or something for changing system volume and getting the current volume id be great full! plus.
I want to be able to change (Increase or Decrease) the computers bass, Main volume, view connected audio devices (Output Devices) and finally display the computers volume with a progressbar.
How can I control the volume of only the sound coming from my program rather than the system sound with a track bar? If this isn't possible, how can I control the system volume with the track bar?Bgeo99
I have been surfing the net all night to try and just learn how to do what I think should be a simple thing! How do I in vb.net when I press a button make it so that the windows volume changes to 50%? Is this that hard to do? Why cant it be like "windows.volume = 50" or something?
I'm making a media player that is using the Windows Media Player component and I have the visible property set to false. I'm going to make all of the controls but one I'm having trouble with is the scroll bar. with the scroll bar if you move up the track bar up a little it should increase the volume like the one on the component. The code that I though was AxWindowsMediaPlayer1.CtlControls. but there was nothing there that could be used to control the volume.
Here is simple and effective code using API acting like Windows volume control, you can use to increase, decrease or mute overall computer volume
[Code].....
ok so i got this from someone and it worked but i was wondering how i could find out or if you know what uinteger would allow me to increase my volume by a greater amt and decrease it by the same amount?
So I'm a bit new to the whole Vista/7 audio setup. My understanding is that a new "mixer" is created for each application. Is there some new .Net function which interfaces with these mixers? I'm actually trying to create an application which can adjust the MAIN system volume level as well as the mute function.
I was looking at the Endpointvolume API however I cant get it to work for me :(. Does anyone have a vb.net demo of how to harness this API?

I need to control the main computer volume in vb.net. I have searched the web and tried all the examples I could find. None of the have worked.Does anyone have some snippets of code that work with vb.net 2010 to control volume?
here is the problem : in vb i added the volume meter dll and did :project reference to add : progressbargradient.dll, Microsoft.DirectX.dll, and Microsoft.DirectX.DirectSound.dll
and connected webcam with microphone but i get the error "Microsoft.DirectX.dll' is attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang."
There are lot's of examples for volume control in VB6, however, I can't get them to work inside VB.NET!! how to get and set volume control (WaveOutGetVolume, WareOutSetVolume) in vb.net.
i want to make an application that i can control the volume just like the volume icon on the taskbar. i did search and only find way to call volume setting using Call Shell("C:WINDOWSSystem32sndvol32.exe", 1)
this is not what i want. i want to call just one volume control trackbar only like the one on the taskbar.
I ma playing an audio file using: My.Computer.Audio.Play("C:soundsmouseclick2.wav", AudioPlayMode. Background). I want to specify the volume, all i need to be able to do is enter the number via code, i don't need to use any sliders etc. Is there anything simple like: (this is an example of course) [Code]
I tried to implement Trackbar1 with Windows Media Player. The volume stays at the same sound level no matter how much I move the slider. Here is the code.
