Please tell me how. I use DVD Audio Extractor.
When ripping Blu Rays:
Use
MakeMKV
When you load disc in your BD player and populate with MakeMKV you will see a selection True HD Atmos, LPCM stereo, Dolby Digital 5.1.
This is not all the time, but in general. Quadio Blu Rays only have stereo and Quad as an example.
Some Blu Ray rips are hard to figure out the sequence of the rip especially if they have instrumental versions etc.
When in doubt, rip all, look at the rips, click on one, and your right side pane will likely show you what you have ripped.
When I was a novice, I would put Blu Ray in player, take picture of menu with my phone, but I don't need to do that anymore.
Every disc I own, never see's a player at this point.
In my case I use JRiver as the player via USB for stereo and multichannel to AVR and HDMI to AVR for Atmos playback.
Atmos files all MKV and non Atmos files all FLAC.
Next step is use Music Media Helper for tagging, etc.:
