i think i found whats causing the issue. for some reason windows thinks that the device is constantly in a call. it then decides to mute the volume.
turning it off has solved this issue for me. might help
Just to let you know I have the same issue as you all, with sound fluctuating when I'm using the built-in speakers. I haven't found a fix yet, but I haven't tried to disable the NVidia stuff. I'll let you know if it solves the issue. I've seen plenty of people complaining about the sound, I'm a bit disappointed for a 2500$ computer 😞
Also, does anyone know where I can get the ROG HD audio manager? Can't find it on the drivers page.
Thanks a lot
I disabled NVIDIA High Definition Audio under Device Manager -> Sound, video, and game controllers and then rebooted. So far so good. Will post an update in a day or two letting everyone know if it sticks.
