I've seen similar messages in relation to this; however none have helped, so I'm starting my own. I hope someone can help. I upgraded from Windows XP to Windows 7 64 bit. In XP, I used the headphone jack on the front panel to connect to TV or headphones. Since I've updated the headphone jack does not work. The 'Manage audio devices in control panel displays the headset is plugged into the front. The microphone works well. I tried searching for updated drivers - I have the most up-to-date. I tried changing the BIOS settings to HDAUDIO AC97 - does not work. I tried to install the SoundMAX High Definition Audio Utility installation disk my motherboard, but Windows 7 will not let me run the setup program is not compatible with the operating system.
