Please help! I'm going mad trying to fix this. I have a HP Pavilion p7-1436s Desktop PC with windows 8.1 64bit installed. The audio has stopped working. I have IDT High Defintion Audio CODEC installed in my system. My warranty expired last year 
The little white icon of a speaker has a red circle with a white X. When I click it I get an error message saying 'one or more audio services are not running-not fixed'. When I check the IDT audio it shows it's enabled and that I have the lastest driver update. Why is it doing this?? I tried downloading other audio drivers and get a message 'this device is not supported by your hardware, install will abort'.
