This was a problem with 2018 as well and hasn't been fixed for 2019. Whenever a Blu-ray disk with Dolby TrueHD or DTS-HD audio is played that has surround sound, the volume is always set to 100% and can't be adjusted or muted in PowerDVD. Only changing the entire system volume (or muting all sounds) can the volume be adjusted.

I'm running 5.1 surround on a X299 motherboard through the onboard Realtek HD Audio. Blu-ray disks with stereo sound and DVD disks with surround (Dolby Digital 5.1) do allow for volume control.

If you want powerdvd to control the volume when playing your movie disc, de-select the WASAPI output in powerdvd settings -> video audio subtitle -> more audio settings.

The setting is off. Turning it on makes it so that all volume controls are through the system volume. With it off, the problem remains that DVDs & stereo Blu-ray disks have adjustable volume, but Blu-ray 5.1 audio does not.

Also for those Blu-ray 5.1 audio playback, no sound level is shown going to the speakers as though it's bypassing the normal Windows sound processing (usually DirectSound). I suspect this is somehow by design when feeding sound through HDMI, but causing a side effect when using analog out from Realtek audio.
