Distorted sound using DirectSound on USB Audio Device (Creative Xmod)

Hi

I'm having issues with my Creative Xmod using DirectSound on one of my PCs.

The sound sounds heavily distorted when playing at a low volume, and there's quite a lot of white noise at higher volumes. This leads me to think it is some sort of quantization noise.

DxDiag has the following to say about my card:
Code: [Select]
            Description: Creative Xmod (emulated)
 Default Sound Playback: Yes
 Default Voice Playback: Yes
            Hardware ID: USB\Vid_041e&Pid_30d0&Rev_0100&MI_00
        Manufacturer ID: 65535
             Product ID: 65535
                   Type: Emulated
            Driver Name: 
         Driver Version: 
      Driver Attributes: 
            WHQL Logo'd: 
          Date and Size: 
            Other Files: 
        Driver Provider: Microsoft
         HW Accel Level: Full
              Cap Flags: 0x2F
    Min/Max Sample Rate: 100, 100000
Static/Strm HW Mix Bufs: 0, 0
 Static/Strm HW 3D Bufs: 0, 0
              HW Memory: 0
       Voice Management: No
 EAX(tm) 2.0 Listen/Src: No, No
   I3DL2(tm) Listen/Src: No, No
Sensaura(tm) ZoomFX(tm): No
               Registry: OK
      Sound Test Result: Not run


What stands out here is that DirectX treats the sound card as emulated. When testing the same card on one of my other computers, DxDiag does not say "emulated" and the type is WDM.

I've googled the issue quite a bit and also tried applying this fix without any luck.

If anyone know how to deal with this problem, please let me know :-)

Best regards
Anders

Distorted sound using DirectSound on USB Audio Device (Creative Xmod)

I found a solution.

My computer is a Dell Precision M4400 (laptop) and with the onboard IDT Audio sound card drivers a service was installed. This service monitored the jack connectors, but more importantly, it "held" the WDM audio stack (in lack of a better way of describing it) in such a way that my USB Audio card was not correctly installed.

By disabling the audio service, installing my USB Audio card and reenabling the service, everything now works great.
