I can't get any sound out of my (stock) HP Pavillion G4. (well, except for a special case...)
How do I accomplish a complete delete and re-install of all of my sound drivers so that I can start from scratch and try to get my sound back??????? (and where do I get the update software for all three?) It might also be my Registry file is corrupted, so how do I check (or reset) all those settings?
History:
I had been getting Windows 7 Blue Screens of Death (after a #$%&ing Skype 6.18 automatic update, which was absolutely proven to be the cause of the BSODs, btw) , so it was time for a complete, clean reinstall of Windows, including a complete hard-drive wipe. After the re-install, initially, I had no problems. Then, suddenly, after the bazillionth @#$%^ Windows update, the sound stopped working. It is also possible that, somehow, when I ran my Eusing Registry Cleaner, that some audio registry setting got fouled up.
When I go to Device Manager, I see three Sound items: ATI High Definition Audio Device, IDT High Definition Audio CODEC, and Cyberlink Webcam Virtual Driver. However, when I use the SRS Audio Control Panel, the ATI HDMI control is greyed out, and I can't change it or access any control of it. I tried to update the ATI driver, but it said it was up to date. I tried to delete the ATI driver, and then when I ran 'Scan for Hardware" in Device Manager, it apparently saw the ATI hardware and brought the ATI driver back (version 7.11.0.7706, dated 5/6/2010). When I go to the Sound Manager in the Control Panel, it says that the ATI HDMI Audio Output is "Not Plugged In".
The only way I can get any sound, which says that the hardware actually does work correctly, is to "Test" using the IDT device in Sound Manager (Playback)
