Hi chewitt ,
thank you for the clarifying. But currenly I'm little bit confused and get a node in my head. Do you have a perhaps a link to a sketch about the different positioning of SL/SR vs. BL/BR vs. BLOC/BROC speakers please?
I'm asking because my DENON 3808 AVR reports this setup via HDMI (EDID decode) and thinking the SONY AVR of _marklam_ behaves the same :
Speaker Allocation Data Block:
FL/FR - Front Left/Right
LFE1 - Low Frequency Effects 1
FC - Front Center
BL/BR - Back Left/Right
BC - Back Center
RLC/RRC - Rear Left/Right of Center (Deprecated)
This 7.1 AVR has 6 terminals for 2x Surround A + 2x optional Surround B and additional 2x Surround Back Left/Right speakers. The Surround A terminals should be used for a 5.1 setup and the speakers placed sideways or little bit behind of the main seating.
Currently I think BL/BR is mapped to Surround A + B and RLC/RRC is virtual in 5.1 mode. Because I currently haven't a 7.1 speaker setup I can only relies on the reported input signal.
In that sketch for the 7.1 speaker setup example, it looks to me
https://www.intel.com/content/dam/support/us/en/images/mini-pcs/7.1.jpg
- that BL/BR is moved to my assumed RLC/RRC position
- and SL/SR replaces my assumed BL/BR position
During my research I found this kind of adapters too: https://www.allaboutadapters.com/au-hcp2.html I'cant see a different positioning for SL/SR vs. BL/BR
I'm wonder if AESinkALSA should doing the same with LPCM 7.1 media files?
- map media SL/SR -> HDMI BL/BR channel
- map media BL/BR -> HDMI RLC /RRC channel
Being I'm totally wrong with that idea? Or does all others 7.1 receivers advertise SL/SR via HDMI additional?
EDIT:
HiassofT Could it be that there is already an option for that, but a condition is wrong (channel replacement looks not executed)
