cPlay outputs 32 bit audio to the soundcard driver. On startup, if the driver doesn't support 32 bit, cPlay reports an error and will not allow for any playback.

Driver converts 32bit format down to 24 (or 16) either at sw or hw level and may apply dithering if needed.

Based on the problem experienced, that driver needs to be either reinstalled or may have a bug. There could also be an issue with 64bit Windows - here, cPlay must be run in 32bit mode.

  cics, I have not been able to get cPlay to play .wav files that I have ripped from DVD-A's using DVD-A explorer although i have been successful in playing high rez .wav files ripped from DVD-V's.
  
  Is there something different about the DVD-A .wav files that is not compatible with cPlay?
  
  Thanks,
  
  Jack

    Look at "Diagnostics" messages. There should be a reason given for why the wav file was rejected.

      cics, the error message I am geting from these wav files is:
      
      Wav file is NOT supported.
      Only 16, 24 or 32 bit (PCM or IEEE754 Float) uncompressed stereo (at any sample rate) is supported.

      • Most likely problem: it's a multi-channel wav file (cPlay only supports stereo) - cics 08:50:49 11/06/09 (2)

        You can use SoX to check your file. Download "MS-Windows executable", unzip folder and copy the 2 dll files (cygwin1 & cygomp-1) to c:\windows. Command from a command prompt is:
        

        c:\mysoxfldr\sox.exe --i "c:\my long name folder\My Wav.wav"

        
        
        Output would be something like this:
        

        
        C:\> sox --i "c:\music\01 Track01.wav"
        
        Input File : 'c:\music\01 Track01.wav'
        Channels : 2
        Sample Rate : 44100
        Precision : 16-bit
        Duration : 00:02:39.73 = 7044240 samples = 11980 CDDA sectors
        File Size : 28.2M
        Bit Rate : 1.41M
        Sample Encoding: 16-bit Signed Integer PCM
        
        
        C:\>

          It may be different wav format and SoX may help in converting it back to the old wav format.
          
          Try following:

          sox "MyTrack01.wav" "NewTrack01.wavpcm"
          
          rename "NewTrack01.wavpcm" "NewTrack01.wav"

          
          
          Test cPlay with "NewTrack01.wav".
          
          In cMP Settings, set RAM Load to "No" and both Suspend svchost & lssas to "No". What soundcard are you using?

          Thanks cics. I"ll try your suggestion but I am pretty certian that the files I ripped from the DVD-A's were the stereo track. I will follow up if my SOX output confirms this.
          
          Another problem I am experiencing id that when I try to use cPlay while in CMP-2 it appears that CMP/cPlay recognizes and loads all of my .wav and .cue files but I cannot gey them to play. I have no problem playing the .cue files when nCMP is not loaded when I select hem directly from my music file directly so I know it's not the files themselves but perhaps the path to them?
          
          I seem to have a similar problem when I create a playlist with cPlaylisteditor. I cannot get the saved file tp play in cPlay.
          
          Thanks again for any help you may be able to lend.
