I have installed a new H.D.
The rest of the components remain the same.
Using ITunes or Media Player, when I try to play a CD, the computer reads the tracks but no sound.
Screen pop up reads - ‘problem with sound device’
Motherboard is ASUS P4P800 / M370. Contains the audio.
Reloaded ASUS M.B. CD but still no sound.
If I reconnect old Hard Drive to computer I get sound.
Please advise what is the problem and how to fix ?
