Hello,
One of my rooms has an older TV that lacks EARC/ARC. I’m going to be upgrading the TV sometime this year, but the soundbar I was using with it died. I was going to buy an Arc Ultra with the new TV but now I’m considering getting an the Ultra early but I would have to use it with the HDMI to Optical adapter temporarily until I purchased a new TV. I know the Arc Ultra will work over Optical, just be limited to Compressed 5.1.
My question is in regards to the speakers. If using Optical and only getting Compressed 5.1, will is still use all the speakers in the Ultra? For example, will the up-firing speakers just not produce any sound at all if the Ultra is receiving a 5.1 signal, or will they duplicate sound from one of the front channels?
Thanks.
