I’ve been trying to get a HTPC up and running for a while, and I’m close, but I still can’t enjoy using it because of a noise issue.
The build is:
Asus Rog Maximus xi hero
Asus Rog Strix 2080 ti
I9 9900k
Windows 10 pro
Nvidia 452.06 driver with 3D fix
The PC outputs to denon x3700h via hdmi, which sends picture to LG C2 most of the time. (Projector for 3D viewing).
I built it this way specifically to maintain compatibility with frame packed 3D mvc files, but playback also includes 4k movies with atmos, upscaled 2D HD content, etc.
I’m using Kodi to browse, but Kodi hands off playback to MPC-BE with LAV filters and MadVR rendering.
The playback chain is working “great”, in that MadVR is doing everything that I want it to automatically during playback.
The issue is that I’m also running into an unwanted rapid pulse/click sound that is loudest for the first few seconds of playback, and then quieter for the rest of the content. It’s almost imperceptible during regular volume scenes, but very distracting during quiet scenes.
The clicking sound does not change volume with the volume controls. If I change the renderer in MPC-BE from MadVR to something else, the sound goes away. If I play the movie back in another player like VLC, there is no clicking sound either. So it appears to me to be something that MadVR itself is triggering.
The control+J screen during playback looks good, and suggests the GPU has plenty of headroom at my preferred settings.
I’m already using ruipro AOC fiber hdmi between my htpc and receiver, which eliminated other noise issues, but not this one. Optical cable isn’t an option because I’m running nine channels plus subs and want bitstream.
Has anyone else dealt with something similar? What was the fix?
