    DisplayPort audio issue with Windows 10


    I'm using a Surface Pro 2. After my upgrade from Windows 8.1 to Windows 10, I'm not getting any audio out from the DisplayPort.

    I use DisplayPort to HDMI to a receiver. I've upgraded to the latest RealTek audio drivers, but it's not helping. Could there be a different driver issue at play?

    Any suggestions appreciated.

    No audio through DisplayPort

    No startup sound when login password is active (DisplayPort connected monitor speakers)

    Hello. I assume it is related to analog/digital output or system prioritization. I feel like if there is password, Windows does not play the sound through DisplayPort because it is named AMD High Definition Audio Device (prioritization or does not send the audio at all).



    Does anyone have a logical explanation and/or a possible solution to this?



    • Monitor speakers (DisplayPort) + account password: There is no startup sound
    • Monitor speakers (DisplayPort) + no account password: There is startup sound
    • Analog headphones (3.5mm jack) + account password: There is startup sound
    • Analog headphones (3.5mm jack) + no account password: There is startup sound

    Thank you.
