Hi guys

 

 

 

Ive googled around but havent been able to find a straight answer on this one.

 

 

 

I have a Sony TV that has optical out connected to my pioneer receiver. This appears to give me 5.1 from freeview which is good. My question is, my Xbox one is plugged into the tv via HDMI and not directly into the amp so sound goes out the xbox, through the tv and out the optical to amp.

 

Will I get proper surround sound this way or will I need it connected separately to a different channel on amp?

What is the make/model of the TV? If there is a setting, it will mention either 'passthrough' for your amp to decode or there will be no setting which will mean it may just downmix to two channels.

 

It is always best to have all peripherals go into the amp, then the amp passes the video to the TV.

You won't get 5.1 PCM (or anything above 2ch bitstream IIRC) out of it, at best you'll get 5.1ch dolby or 2ch PCM, you're much better off using HDMI passthrough with the receiver.

Ok so I have set the xbox to output dolby digital through hdmi and the tv to "external receiver" and it looks like the amp is picking up a dolby signal through freeview and netflix on xbox so I guess thats a win? it sounds pretty good.

So basically, HDMI lets alternative audio formats like uncompressed 5.1ch and the newer Dolby formats through, whereas Optical only does some of the more basic Dolby formats in 5.1ch and the rest in 2ch uncompressed.

 

HDMI audio is the better option, but use whatever suits you, if you're not an audio fiend you probably won't notice/care.
