We need alot more information to correctly answer this question, audio is usually not completely handled by the processor alone, there are seperate audio processors built into the systems motherboard. you will need to know the manufacturer for your pc, and the model number, with that information you can likely go to your models support page and download the audio drivers, which is likely what is missing. you can usually easily find the support page for your model by simply doing a good search for your pc manufacturers name followed by support. Good luck and I hope this helps.
