hdmi arc if you want to use cec this makes it so that your tv remote can control your soundbar or audio video receiver and vice versa if you have a NUMBER_TOKEN channel or less soundbar or surround sound system it really doesn't matter which one you use both are going to output a compressed audio stream that's exactly the same but if you have any upward firing or ceiling speakers that are set as height channels then you'll definitely want to use hdmi arc as digital optical will not support these height channels at all so if you have adobe atmos sound bar use hdmi arc never digital optical again even with hdmi arc you're still getting a compressed audio stream there's no way to send more than two channels of uncompressed audio through hdmi arc it's just not capable of it now if you have hdmi e arc then that's a completely different story just go watch my video on hdmi arc and it will explain everything you need to know about it but to keep it really short hdmi er supports both adobe true hd and dts hd master audio both of which offer more than NUMBER_TOKEN channels of uncompressed audio and NUMBER_TOKENd object-based effects which is adobe atmos and dtsx that's a lot to say i hope that makes sense i also want to clear up another bit of confusion about hdmi arc that's very important when you have a media device connected directly to a sound bar or av receiver with an hdmi cable you are not using hdmi arc to send the audio so all of these limitations that i just discussed do not apply when the media device is directly connected like this the only bottlenecks for audio quality are one what the media device is capable of playing to the source of the media so a blu-ray disc netflix hulu etc most video streaming services support up to dolby digital plus by the way and three the last bottleneck is the soundbar or av receiver itself naturally they will only play what they're capable of receiving i hope this clears up any confusions about both digital optical and hdmi arc if you learned something or found this video helpful i'd really appreciate it if you'd smash that like button as always i'll see you guys in the next one bye
