Have You Checked Master Volume control. Checked Windows Audio Service is
started. Checked Device Manager for bad drivers. Checked your audio mixer software (if
installed) for a setting that mutes back panel audio if you have plugged headphones into a front
panel audio jack. .....Uncheck this setting to allow audio to both the back and front. Checked BIOS to insure on-board sound is enabled. Installed the correct Chipset and Audio
drivers. None of that worked? Have you tried this? The Universal Audio
Architecture (UAA) High Definition Audio driver for Windows may be corrupted or causing problems
with the audio driver installation. To resolve this, try the following: 1. Click Start
> Control Panel > Add/Remove Programs. 2. Look for the following two items: Realtek High
Definition Audio Driver and High Definition Audio driver Package - KB888111. 3. If these items
are listed in Add/Remove programs, remove them. 4. Restart Windows. 5. Download the latest
audio driver for your PC. 6. Double-click the filename to extract the files. 7. Go to the
folder where the files have been extracted and browse to the \HDAQFE\xpsp2\us\ folder or the
\MSHDQFE\Win2K_XP\us\ folder. (The name of this folder depends on your PC model.) 8.
Double-click the file kb888111xpsp2.exe to install the High Definition Audio Driver Package. 9.
Restart Windows. 10. Install the audio driver.
