The P5Q is a Socket 775 motherboard made by ASUS. It comes with a built-in Realtek 8-channel high-definition audio codec that uses an internal converter to translate digital signals to analog audio, and vice versa. If the ASUS P5Q fails to emit sound, the high-definition audio setting in the basic input/output system (BIOS) program could be disabled. Speaker configuration can also make it seem as if the ASUS P5Q is failing to play audio. To fix the audio problems on the ASUS motherboard, troubleshoot the BIOS and check the speakers.
Instructions
1. Power on the ASUS P5Q and press "Del" or "Delete" to boot to the BIOS Setup Utility. The BIOS, or basic input-output system, is an interface with the motherboard's firmware. Use the arrow pad to go to the "Advanced" tab.
2. Scroll down to "Onboard Devices Configuration." Press "Enter" to open the submenu.
3. Select "High Definition Audio." Press "+" and "-" to change the option to "Enabled" if the setting is configured as "Disabled."
4. Scroll to "Front Panel Type." Use the "+" and "-" keys to select "HD Audio" or "AC97," depending on which specification the front panel audio component supports. Consult the documentation included with the component if you aren't sure which one to select.
5. Go to "SPDIF OUT Mode Setting." Use the "+" and "-" keys to toggle between "SPDIF Output" or "HDMI Output." Select the latter option only if you have a video card with HDMI support and are using the SPDIF signal for the high-definition monitor's speakers.
6. Press "F10" to save your changes and exit from the BIOS.
7. Connect the speakers to the lime green Line-Out port on the back or front of the computer. Confirm the speakers are powered on and that the tuner is not set to its minimum setting.
8. Boot in to the operating system. Check the volume tuner to confirm that the sound is not muted in the OS, then test the sound.
