Applies To:
  • CitectSCADA 5.5x
  • CitectHMI 5.5x
Summary:
No sounds play in Example project when the default installation path for Citect 5.50 is used (c:\Program Files\Citect). 

Solution:
Citect has confirmed this to be a problem in CitectHMI/SCADA version 5.50. This problem has been fixed in version 6.00.

The PlayWav() Cicode function needs to use a different format to support paths or filenames containing spaces. The space in the path causes a call to the DspMCI play command to fail. This can be fixed in version 5.5x by modifying the PlayWav() function in the mmedia.ci file in the Example project.

Change line 26:

Original: sCommand = "Open " + sPath + " Alias WAV type WaveAudio";

New: sCommand = "Open ^"" + sPath + "^" Alias WAV type WaveAudio";
