Audio output FAQ

Question: CD Scratch reports "Error initialising audio sub-system!". What does this mean?

Answer: You must have Direct X 5.0 or above installed on your system, and be running Direct Sound (VXD) or WDM drivers for your sound card. If your computer does not have both of these requirements, you should download the latest drivers for your soundcard, and or go to to download the latest Direct X version. If you are not sure if your computer meets these requirements, seek some advice from your computer supplier.


Question: The audio output sound warbles and/or pops. What can I do?

Answer: First thing to try is calibrating your sound if you are using the WDM driver type (does not apply to legacy mode).For instructions on calibrating your soundcard click here.


I still can not get it to sound right, no matter where I put the calibration slider. What next?

Answer: You may have the choice of using the "legacy", "WDM", or "Compat" driver types. Try changing to the other available driver types. Click here for details.


I have tried calibrating the WDM driver type, and accessing the other driver types, and neither have given me stable sound. What now?

Answer: Some hardware is designed poorly and will not function well with CD Scratch. Sometimes this is simply due to the drivers installed, and by downloading the latest drivers for your soundcard, you can often alleviate any problems. To do this, go to your soundcard manufacturer's website, download and install the up-to-date drivers. This may take some trial-and-error to find out the best drivers for your system. If you do not feel comfortable with this, seek the assistance of your computer supplier.

Note: Some on-board soundcards are low quality products and have badly written drivers. You may find you have no success even after installing the latest drivers. If this is the case, then you may want to look at PCI or USB soundcard. It is highly recommended that this avenue is explored through a computer dealer so that testing with the CD Scratch can be attempted before making a financial commitment.
