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.
if your soundbar has multiple hdmi ports try plugging your apple tv into the first port and use the second port between your tv and soundbar. maybe it’s tv/soundbar in first port and atv in second. try it out :)
My soundbar has 2 hdmi ports. One for hdmi arc out the other one is hdmi. My apple tv has only one hdmi port. Apple tv is connected to tv’s hdmi 2 port (my tv would automatically identify the device as apple tv but not anymore no idea why). From soundbar’s hdmi arc out to tv’s hdmi arc in. Also I have optical cable connected from the soundbar to the tv. This setup used to work without a single issue but now it doesn’t and I have no idea why. Also the display screen on my soundbar not working anymore. I can not get audio from hdmi and optical ports. Only audio I can get is via bluetooth. Rarely (again no idea how) optical cable works but also I don’t know how it works without me doing anything. I am planning to take my soundbar to the service but don’t think it’s gonna be solved. Wrote this long maybe you can tell me sth I don’t know lol ty anyways.
