Digital audio delay issue - Oppo 205, Samsung TV, McIntosh MC2200

[dpgstereo]

Just purchased a 85" Samsung Q90T for bed room.
Looking for best audio connection to my McIntosh bedroom system? Having audio delay, only when tv is the source...while streaming. Regular satellite and dvd viewing...no issues.


Bedroom McIntosh system: C2200, MC1201's, B&W 802D's, Oppo 205 dvd, Samsung Q90T tv.

Samsung tv has 4 separate HDMI 2.0 inputs... with HDMI IN 3 (eARC).



Currently have setup as follows:

For watching program satellite tv:
Direct TV box, HDMI output... to HDMI 1 on tv. Video.
Direct TV box, RCA audio out... to RCA input on C2200 in Sat input. Audio.

For streaming on Samsung tv:
For audio...Optical Digital output of Samsung tv....to Oppo 205 digital optical input.
XLR output of Oppo 205... to C2200. (audio delay)

Watching DVD:
Oppo 205...HDMI to tv for video only.
Oppo 205 xlr output to C2200 for audio. Set for PCM.

Issue is... While using tv as source, while streaming...I'm having an audio delay. Audio and video are not exactly matched up.
In Sound settings of tv, under Expert Settings... there is a Digital Output Audio Delay adjustment. (Function is only available when device is connected via HDMI-eARC or SPDIF) Not sure why they say SPDIF, tv has no SPDIF output?

Solution?
Samsung tv has..HDMI IN 3 (eARC)...passes audio both ways.
Oppo 205 has HDMI input. Select Input 3.ARC: HDMI Output on dvd player. (Oppo 205 owners manual says this will work).
Should this work?
By using HDMI cable for audio from tv to dvd player, where I can adjust time delay. (Both tv and dvd player have Digital Audio Time Delay adjustments in menu. However, I think time adjustment is for audio output only? So adjust tv time delay.)


I tried adjusting time delay (using Optical digital cable...tv to dvd player) on Oppo 205 menu...didn't make any difference?
May be to adjust digital audio Output only?

Think if I connect tv via HDMI IN 3 eARC to dvd player's HDMI input..... I can adjust time delay in tv menu?
