    So I am trying out SG video mode (Optimus) on my M18xR2 before I swap to my new GPU(can't really swap since I gotta grind the heatsink and ain't got tools) but my issue is HDMI audio.

    I have my HDMI out hooked up to my tv. I am not getting any audio. There's no intel display audio or nvidia hdmi audio showing up in the sound properties.

    Audio was working fine in iGPU or dGPU mode.

    Is there some setting I gotta change to make HDMI audio to work?

    Using 675M with iGPU.

    Installed new GPU

    DDU drivers > tried drivers from Dell

    Same issue, @j95 any ideas?

    EDIT: Okay, I don't know if it was switching back and fourth from iGPU to SG or ennabling a option called internal hdmi codec that fixed it, but it works now. ;)
