HI. There's no (or, at least I couldn't find it under "Peripherals" section) such option in BIOS. The only thing that gets closer to audio I think is the Azalia Codec, which is currently on "Auto". So: (a) how do I turn off the onboard audio, (b) provided that the onboard audio is off, what should be the status of this Azalia option (i.e. off/on/auto)? Thanks in advance.
