Samsung Q70r HT-R494 no sound


I bought a samsung q70r and I've tried setting up my onkyo HT- R494. The tv recognises the sound system through arc and even comes up with the name but there is no sound. I've tried enabling/disabling atmos but still no sound. I've also tried using optical and plugged my ps4 to receiver but still nothing. I've tried a sound test on the system itself and all the speakers are working fine. It also worked fine on my last older tv the sony xe90. I called samsung and they were useless and basically said the sound system was too old for the tv. Does anyone know how I can fix this? I've inclused a link to the tv and sound system below, thanks.

Hi, sorry I thought I deleted the other thread. Optical works, I can't use dolby atmos with optical though but at least I can still get surround sound.

Remember to never use the HDTV as audio source.

The setup that I see working are HDMI sources (players, etc) to the Receiver then video out of the receiver to the HDTV.

If you attempt to have the HDTV as source you may find it doesn't work. If you are trying a Smart(?) TV running Netflix (read ) if that fails I'm not surprised. That will require not only the app be current but the usual current HDMI cable, firmware and all to be perfect. You will find HDMI ARC failures all over the Internet so your choice to make it a warranty issue. If the makers fail to fix, again your choice to keep or return as defective.

The setup of the usual players, not HDTV as the audio source is where I see Dolby Atmos to work but only if the firmware, source and products do have Atmos.
