Epson LS12000 Files Disable Dolby Atmos #1

Closed kjack9 closed 1 year ago

Hello!

Thank you for creating these, huge help for those of us doing budget home theaters.

I am trying the ezcoo_fw_LS12000_BT2020_ML385.hex on my EZCOO splitter in-line between my source (Fire Stick 4k Max) and my receiver. I have an LS12000 as the output device on my receiver.

While I do get DV capabilities as expected, the Fire Stick reports that the device is no longer Dolby Atmos capable. If I use the generic EZ-SP12H2_ML_385_XNAPPODV.hex, Dolby Atmos reports as available but I understand that I'm losing HDR10+ capabilities.

Note that if I move the splitter between by receiver and projector, I get both DV and Atmos but since the splitter can't handle 4k120 that's not a viable permanent solution for me since I have a PC connected to the receiver for gaming.

Is it possible to update the LS12000 files to add Atmos support? Or maybe a second set that includes Atmos? Or am I approaching this wrong?

Thank you for your help, and for your work on this project!

This is as expected, since the LS12000 version is meant to literally just be the LS12000 + DV. I understand the problem though - you really want one that is after your receiver.
