Problems may occur with audio and system performance on computers with Intel processors and motherboards using chipsets that employ Hyper-threading, SpeedStep (EIST) and/or C-State (C1E; C3; C6) functions. While these functions work to improve power management and energy saving, they can have detrimental effects on the performance of a computer used for SoundCheck. If these options are available on your processor, they can usually be disabled in BIOS. Dell computers do not always allow control of these functions in BIOS so Dell support might need to be contacted.
It is also recommended to turn the Windows Power Management Scheme to high-performance. This can be found in Control Panel > Hardware and Sound > Power Options.
Any audio interfaces using WDM drivers communicate through the Windows mixer. To check on these settings, go to Control Panel > Hardware and Sound > Sound. In the playback tab, find the interface you are using and double click on it. Click on the level tab and set it to 100. Do the same for the recording tab. If these levels are not at 100 you will attenuate all signal entering SoundCheck.
