I have tried all the links to fix my NO AUDIO. Nothing works. I can not find the R2.14, it must be superseeded. I hve an HP zv5330us and I had both Realtek and Soundmax. When I went to Vista I had to remove Realtek, in the registry also. Then SoundMax was great. Went to 7 and not hearing a thing. Any idea where I should look for a remedy? Whenever I go to the HP site it basically tells me to buy a new computer.
