Significant Delay in Optical Audio Output in Wireless One Connect Box

I recently purchased an 85in S95H OLED TV with the Wireless One Connect Box.  Audio from all sources is routed through the Wireless One Connect Box via the Optical port to my Anthem MRX Receiver.  I experience a 3 second muting delay when I change a channel on my cable box.  Very annoying and excessive in my opinion.  So  I began troubleshooting.  I ruled out my Anthem Receiver, because when I change the channel on my cable box, the Receiver displays "No Signal" indicating that the signal from the Wireless One Connect Box is not sending the signal.  I then configured my TV for TV Speakers to see if there is a delay.  I experience less than a second under this scenario indicating to me that one second of the delay is due to the Spectrum Cable Box.  Reconfiguring the audio to play through my Anthem Receiver, I then set the Digital Audio Output setting on the TV to "PCM" instead of "Auto" and that reduced the delay to about one and a quarter seconds.  My understanding is that the PCM setting allows only stereo operation instead of Dolby Digital Surround Sound, whereas the Auto setting allows for Dolby Digital Surround Sound.  This leads me to conclude that the additional 2 seconds of delay is originating in the Wireless One Connect Box.  Has anyone else experienced this phenomenon?  To Samsung:  a 2 second delay to acquire and process the digital audio signal seems excessive to me.  Given that I purchased your flagship and largest OLED, I expected better performance than this.  Is there anything that can be done to remedy this via firmware?   Please advise.
