    Ok have you tried updating the software for the audio device in the Device Manager? If not when you do use the "search automatically for updated driver software" option which will search both your machine and the net for updates.

    Now I haven't come across that Microsoft MUAA before and I see it is a bus driver of sorts for high definition audio maybe it needs installing?

    If you want to try - Microsoft UAA Bus Driver for High Definition Audio Download - TechSpot
