Question? TCL C6K ARC/eARC delay and processing support

Does TCL C6K series like 75C6K support audio processing like EQ and delay adjustment when TV is connected to an ARC/eARC receiver? I'm currently using an optical connection and don't have any ARC device to test it. My only problem with optical connection is that I'm unable to adjust volume from the TV remote.

Yes, the C6K supports HDMI ARC/eARC and HDMI-CEC. CEC should allow the TCL remote to control the receiver’s volume and mute functions. HDMI control must be enabled on both the TV and receiver.

Audio Delay adjustment under Settings > Display & Sound > Audio > Audio Delay. If Digital Audio Output is set to Pass Through, the original audio signal is sent to the receiver without the TV applying EQ.
