I have been using PowerDVD for many years as my only optical disc software player on my HTPC. It has its quirks, but it mostly works well.
I recently upgraded my HTPC with the following components to enable UHD playback in PowerDVD:
1. Intel 9th gen i7
2. Asrock Phantom Z390 motherboard with Intel 630, that supports HDMI 2.0 and HDR
3. LG wh16ns60 drive
I have the HDMI cable connected to a NAD surround sound processor. I use HDMI passthru in PowerDVD and I get Dolby/DTS from the processor. However with UHD movies, PowerDVD 19 isn't letting me pass Atmos. It only sends Dolby 5.1 or LPCM. I see the same on the NAD's display as well.
I emailed Cyberlink and they confirmed that Atmos passthru isn't supported. So while PowerDVD has been adding features like 8K playback etc, if it can't pass thru multichannel sound "as is", then it's a showstopper for me.
Any suggestions or alternatives? I don't want to convert UHD discs to mkv every time, I have to watch one.
