HDMI Multichannel issue (channels randomly swapping)
#1
Question 
Hello Tim
I have an issue that seems to happen only on moode (I run 6.7.1, don't know other versions).
Kernel modded to support 8ch. (bcm2835-pcm.c)
Using the HDMI output, from CLI, every time I do a "speaker-test -Dhw:0,0 -c 8", channels mappings kinda randomly swap.
I mean on first iteration of speaker-test, "0-front left" is really the front left. Then I stop the script, I rerun it and the same channel plays on a different speaker.

I tried raspbios stable and it's not happening there. Same kernel version*, same kernel mods.
*I hope to have built the same version, tried quite a few and could have made mistakes. Will double check.  Double checked, same version from same build both on raspbian and moode and it does it only on Moode.

- Is there something that could cause this on the moode-customization side? or it must be kernel?


Moode 6.7.1 - Raspberry Pi 4B
Raspbian 10.3 | 5.4.51-v7l #1 | armv7l (32-bit)

also tried all of these and no changes
Code:
dtparam=audio=on
hdmi_force_edid_audio=1
hdmi_drive=2
hdmi_force_hotplug=1
hdmi_group=1
hdmi_mode=16
hdmi_blanking=1
dtoverlay=vc4-fkms-v3d
max_framebuffers=2
