As my arc port stopped working immediately after updating to os 17 was waiting to be solved with new update but no. Maybe the reason is not tv os but the weird thing is my soundbar works only with Bluetooth connection since then. Hdmi doesn’t work, optical connection doesn’t work. Gonna tak my soundbar to service let’s see what they gonna say. Also I have my doubts if my tv has an issue or not. Both my tv and soundbar are samsung btw.
Not exactly the same issue but immediatly after 17 update, passthrough via eARC stopped working. Forced to switch to Dolby, if I set to auto my tv don’t passthrough and I have horrible audio delay….
