I accidently reset my LG OLED TV to original factory and when I went to hook up my Samsung Q90 sound system again, it no longer is detected as an ARC connection. The connection type is listed as D.IN and now no matter how many times I have unplugged TV and/or soundbar and/or re-plugged in the HDMI cable or run through the input types on Q90, the system does not register as an ARC connection. Note it used to work fine ... my TV and Q90 are current on firmware updates. I have the system plugged into the correct ports and my HDMI cable is a high quality 4K cable (and again I have been using it for 4 years). Please help ....
