Hi,
Need to confirm if I send Dolby True HD or DTS-X signal to TV with only Arc connection will it downgrade it to DD 5.1 / DTS HD or just straight to 2 channels? Or I simply won't get any sound?

Looking at Bose 900 or Sonos ARC, not going for rear speakers. A7000 a bit too expensive. So it will be from player direct to tv , then tv to soundbar.

I have LG C8 which doesn't hv e-ARC, My movie collection played thru Zidoo Z9X connected to NAS.
Some of the files only have DTS codec.

Both Sonos and Bose 900 does not have hdmi in ,so I hv to route Zidoo to Tv first.

My LG C8 still support DTS pass through, just no e-arc.

Im not sure, if sending True HD or DTS-X signal to the tv , what type of signal will be going to the soundbar.
If it’s converted to ‘lower’ quality that’s one thing , but if it’s not giving any output then I hv to consider other soundbar.
