    Question GL504GM - no HDMI audio device at all and can't run nVidia control panel

    I have a ROG Strix Hero II laptop, about a year old. FOr the first time I tried plugging it into my TV via HDMI, but there's no audio.

    I went to change the audio to HDMI and it's not listed. The only audio device listed is the realtek speakers.

    I reinstalled the nVidia drivers (clean install) but no change.

    I checked the device manager and there's no device showing for nVidia audio. I checked audio devices and nothing is listed, disabled, hidden, or otherwise.

    I have the latest drivers from nVidia and GeForce experience runs fine. Everything else works.

    EXCEPT - nVidia control panel won't run. It's in the start menu, but I select it and nothing happens.

    I googled for solutions but nothing I found works, or seems strictly relevant - they all assume you at least have the device listed somewhere, or just suggest reinstalling.

    So I decided to try installing the version from the ASUS website for my specific model, which says it's Version V25.21.14.2546
    2020/05/25. When I ran it, it complained "The standard NVIDIA graphics driver is not compatible with this version of Windows." and suggests installing it via GeForce experience (which is what I already have). So no joy there either.

    Ideas?

    Hello Philomorph,
    Do you have another device you can connect your HDMI to cross check?
    And what brand and model is your TV?
    Thank you.
