I managed to set the Audio Output to HDMI plus Non-decoded high definition audio to external device.

When playing a Blu-ray disc with a video with Atomos, Atmos sound could be output to my external device properly.

However, when playing other MKV/MP4/ISO files, the audio setting "Non-decoded high definition audio to external device" disappears and only "Non-decoded Dolby Digital/DTS audio to external device" and "PCM decoded by PowerDVD" remain.
I'm sure these MKV/MP4/ISO files are enabled with Atmos and they could be output with Atmos property by other player software such as VLC and MPC.

Hello,

From what I know, PowerDVD does not claim support for ATMOS or its pass-through (no ATMOS logo on the web page is a real indicator), so there is no guarantee of the playback compatibility. Which is why it would be played as backward compatible's Dolby TrueHD if the ATMOS passthrough does not work.

However, you should contact CL customer service to confirm. See the links in my signature.

My apologies for resurrecting an old post. I just wanted to post a correction that may be of use to others.
Bitstreaming/passthrough via HDMI does not need for Atmos to be supported. It's all just bits. PowerDVD does not need to know what the bits are, or what the audio codec is.

That PowerDVD will not decode Atmos and output via pcm is another story, and as far as I know is unsupported.

If the AVR supports Atmos decoding, and bitstreaming is done via HDMI, then all is good. I do it every day with a 7.1.4 Atmos system, and PowerDVD22 Ultra is my primary music & video player.
...and quite a capable player it is.

Thanks. I hope this helps someone.
