Sounds with C#.NET CF

Sounds with C#.NET CF

  Hi Pal

  That depends on the device. If your device has a Media Player application capable of playing WAV files I'd do this.

  Copy some WAV files with different encoding setting (8/16 bit, mono/stereo, 11.5kHz/22kHz/44.1Khz sampling rate) and see which one plays fine and which don't.

  Hope this makes sens

  I'm using the same code but I'm just getting a short beep instead of my sound (using HTC TyTN and WM5). What am I doing wrong

  Just use the following code. You will of course have to modify unless you only want to play a notify wav

  public void PlayNotify()
  {
  try
  {
  PlaySound(@"notify.wav", IntPtr.Zero,
  PlaySoundFlags.SND_FILENAME | PlaySoundFlags.SND_ASYNC);
  }
  catch (Exception e)
  {
  //Handle exception here
  }
  }

  public enum PlaySoundFlags : int
  {
  SND_SYNC = 0x0000, /* play synchronously (default) */
  SND_ASYNC = 0x0001, /* play asynchronously */
  SND_NODEFAULT = 0x0002, /* silence (!default) if sound not found */
  SND_MEMORY = 0x0004, /* pszSound points to a memory file */
  SND_LOOP = 0x0008, /* loop the sound until next and PlaySound */
  SND_NOSTOP = 0x0010, /* don't stop any currently playing sound */
  SND_NOWAIT = 0x00002000, /* don't wait if the driver is busy */
  SND_ALIAS = 0x00010000, /* name is a registry alias */
  SND_ALIAS_ID = 0x00110000, /* alias is a predefined ID */
  SND_FILENAME = 0x00020000, /* name is file name */
  SND_RESOURCE = 0x00040004 /* name is resource name or atom */
  }

  [DllImport("coredll")]
  public static extern bool PlaySound( string szSound, IntPtr hMod, PlaySoundFlags flags );

  You’re specifying wrong path to the file (e.g. have drive letter in it or using relative path which is not supported on devices), file does not exist or file is not in the acceptable format. The only acceptable format is uncompressed PCM.

  Have you tried searching for "Sound" here It returns bunch of usefull results with code samples and references to sound libraries you could use:

  But that didn't work either... i.e. to change action type to content

  Did you check all these things I've mention in the previous post

  I've got a simular system in my apps, however it doesn't work if you try to play two sounds at once, (like music and a sound effect), does anyone know if it is even possible to play two or more sounds at once ( knowing that the sound buffer in PDAs may not support it)
  
  

• _Pero_

  Yes, I had try, but the result of search return me evry time a error...

  anyway Thanks

  It seems like I didn't use the resource as embedded though my reference string to it was using that syntax. However, it still doesn't work.

  Build Action: Embedded Resource

  The namespace is MyNS, the class is called Sound, and the file mysound.wav. The resource string would then be "MyNS.Sound.mysound.wav" - right That doesn't work....

  Neither does it work to use Copy To Output Directory: "Copy Always" and only "mysound.wav"

  This is a native function, it can't access managed resources. Either don't use resources (change action type to content so file would be deployed to the device) or load resource data into memory buffer and use different set of flags to play buffer content.

  Thank you Michael,

  It was more of a hardware thing. I got the fix from the manufacturer .

  Thanks a lot for the support.

  It is possible to play multiple sounds at the same time but you would need to use waveOut* API which are low level and require you to parse WAV file yourself. I believe OpenNetcf.org has a managed wrapper for that. Or you can wrap it up yourself if you have the skills.

  Hi Ilya,

  I am trying to add Beep to my WinCE 4.2 application. I tried with both "MessageBeep" and "PlaySound" API's using interop. I could get them work on Emulotor but not on actual device. Is there any way to test playing sound file on device Or do I need to configure any perticulars to achieve the same

  Thank you.

  Pal
