Hi,
since i am stick with this issue too i would like to contribute my findings.
My Setup:
TV: Philips 55OLED806/12
Soundbar: LG SPD75YA
Vero4K running on latest FW (7/23)
The TV is connected to the Soundbar through HDM2 (eARC) Channel
Vero4k sits on HDM1 Port
First of all i got these weired standby issues of Vero4k and CEC stops working. Bit i think i could fix them by setting the behvaiour of the standby command to the Vero 4k to igonre. So no more red light if i switch of the TV.
But the eARC connection seems to have stopped and no audio from the soundbar and if i activte it from the TV the CEC functions (button pressing to go through menus seems to be buggy too.
I was running cec-client on the vero4k to see whats going on and i see:
DEBUG: [ 89905] device Audio (5) status changed to present after command set system audio mode
DEBUG: [ 89905] >> Audio (5) -> Broadcast (F): set system audio mode (72)
TRAFFIC: [ 90736] >> 5f:84:20:00:05
DEBUG: [ 90736] Audio (5): physical address changed from ffff to 2000
DEBUG: [ 90737] >> Audio (5) -> Broadcast (F): report physical address (84)
TRAFFIC: [ 91549] >> 5f:87:00:e0:91
DEBUG: [ 91549] Audio (5): vendor = LG (00e091)
DEBUG: [ 91549] replacing the command handler for device 'Audio' (5)
DEBUG: [ 91549] Audio (5): CEC version 1.3a
DEBUG: [ 91549] Audio (5): menu language set to 'eng'
DEBUG: [ 91549] >> Audio (5) -> Broadcast (F): device vendor id (87)
So it seems that Vero4k will take control of the soundbar and not the TV. And after that i could hear audio from the soundbar.
I am realy no expert in CEC and eARC but is this intended?
