           Summary: Sound crackles on a USB headset when Desktop Effects
                    are enabled
           Product: kde
           Version: unspecified
          Platform: Archlinux Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: AngryKoala at archlinux.us


Version:           unspecified (using KDE 4.8.0) 
OS:                Linux

When playing sound via PulseAudio or ALSA in KDE 4.8, there are crackles
whenever any Desktop Effect is activated.  Turning off Desktop Effects almost
completely mitigates the issue.  Even with Desktop Effects turned off, resizing
a window will have the same effect when sound is playing.

My headset is a Razer Megalodon (USB headset) and the issue is only apparent
using this sound device.  My onboard audio device (Realtek ALC888) does not
have this issue.

Reproducible: Always

Steps to Reproduce:
Resize any window or trigger any desktop effect while playing sound.

Actual Results:  
There is a crackle in the sound.

Expected Results:  
No crackle.
