I have popping or crackling sound when Playing, how do I stop it?
The problem comes from the processor priority that is set when the game is first launched. This issue should be resolved by downloading the latest patch, which you can download from here:
If you are still having problems you can try the instructions below for original workaround.
Launch Tomb Raider Legend and get to the main menu
Hold ALT and press TAB to minimize the game and return to the desktop
Next press Ctrl+Alt+Delete to bring up the Windows Task Manager
Click on the Processes tab and fine "trl.exe" in the list and Right click on it
Left click on "Set Priority", and set it to Normal
Close the Task manager and bring the game back up
The distorted sounds should now have disappeared. If you find the problem still exists follow the steps above again and try setting the priority to "Above Normal".
