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.
View 4 RepliesMute And Unmute Master Volume
May 6, 2009I 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).

Adjust Master Audio Volume Directly Using .net?
Mar 26, 2012Is 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.

View 6 RepliesVS 2008 Get Current Master Volume (Audio) - Win7
Jun 1, 2011It 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.

Inherited Form Trackbar Synchronization
Jun 18, 2010MainForm having a few buttons, VolForm is inheriting MainForm. I can see this perfectly in the designer.VolForm itself contains a trackbar. Now have 2 forms.

Is there any way to keep this trackbar the same in every form that inherits VolForm?

Create A Form With A TrackBar Control : Generate A Frequency?
Feb 17, 2010create a form with a TrackBar control so that when you Scroll the TrackBar it generates a frequency based on the value of the TrackBar. Beep() isn't really what I'm after. I was wanting it to smoothly transition through the frequencies. Basically, I want to create something that sounds something like a Theremin.
I've been looking online, and I can't seem to find anything. I don't even know how this would be accomplished. Is there a simple command to say "play this frequency until I tell you otherwise", or do I need to generate a .wav on the fly and have the system play that?
