Trying to write a PowerShell cmdlet that will mute the sound at start, unless already muted, and un-mute it at the end (only if it wasn't muted to begin with). Couldn't find any PoweShell or WMI object I could use. I was toying with using Win32 functions like auxGetVolume or auxSetVolume , but couldn't quite get it to work (how to read the values from an IntPtr?). I'm using V2 CTP2. Any ideas folks? Thanks! There does not seem to be a quick and easy way to adjust the volume.. If you have c++ experience, you could do something with this blog post , where Larry Osterman describes how to call the

Anyone know how to programmatically mute the Windows XP Volume using C#? Declare this for P/Invoke: private const int APPCOMMAND_VOLUME_MUTE = 0x80000; private const int WM_APPCOMMAND = 0x319; [DllImport("user32.dll")] public static extern IntPtr SendMessageW(IntPtr hWnd, int Msg, IntPtr wParam, IntPtr lParam); And then use this line to mute/unmute the sound. SendMessageW(this.Handle, WM_APPCOMMAND, this.Handle, (IntPtr) APPCOMMAND_VOLUME_MUTE); Mike de Klerk What you can use for Windows Vista/7 and probably 8 too: You can use NAudio . Download the latest version. Extract the DLLs and

I'd like to start and stop HTML5 playback in a random position with fade in and fade out periods to smooth the listening experience. What kind of mechanisms exists for this? Manually ramp up the volume with setTimeout()? The jQuery way... $audio.animate({volume: newVolume}, 1000); Edit: where $audio is a jQuery-wrapped audio element and newVolume is a double between 0 and 1. Edit: The element's effective media volume is volume, interpreted relative to the range 0.0 to 1.0, with 0.0 being silent, and 1.0 being the loudest setting, values in between increasing in loudness. The range need not be

If a user presses volume key up or down is it possible to detect it in my broadcast receiver? I need the full code. Here is my Intent filter IntentFilter filter = new IntentFilter(); filter.addAction("android.media.VOLUME_CHANGED_ACTION"); and my onReceive method is public void onReceive(Context arg0, Intent intent) { KeyEvent ke = (KeyEvent)intent.getExtras().get(Intent.EXTRA_KEY_EVENT); if (ke .getKeyCode() == KeyEvent.KEYCODE_VOLUME_UP) { System.out.println("I got volume up event"); }else if (ke .getKeyCode() == KeyEvent.KEYCODE_VOLUME_DOWN) { System.out.println("I got volume key down event

I am using an applicationMusicPlayer and when i try to change the volume appear the visual notification, as shown in the picture. Here the code I am using: [MPMusicPlayerController applicationMusicPlayer] setVolume:newVolune]; Anyone knows how to hide this notification? I don't know where the docs says so, but if you add a MPVolumeView view to your app the system volume overlay goes away. Even if it is not visible: - (void) viewDidLoad { [super viewDidLoad]; MPVolumeView *volumeView = [[MPVolumeView alloc] initWithFrame: CGRectZero]; [self.view addSubview: volumeView]; [volumeView release]; ..
