Home theater via x1

didn't mean to double.post this... I thought the previous one didn't go through ...

It might be a problem that you are putting the DirecTV feed via your home theater unit. I found this a issue a while back with a TiVo box. My solution was to get an active HDMI splitter and putting a feed to the back of the home theater unit and the other
to the xbox. The other thing you could try is change the sound output setting on the xbox.

SmartGlass for the X1 is a different app than the 360 app, my understanding is that SmartGlass for the X1 will not touch your home network but connect to the X1 via Direct WiFi

Usually a HTiB system has a receiver. Typically it is a built in reciever/DVD or bluray player. Most HTiB systems have a Digital Audio in. It is rare to find a HDMI input on them. Hence why a standalone receiver is better. Oh, now I see. It is just a complete
speaker set. To the OP, as the above poster said, you will need a receiver that would connect all of the speakers. They don't run cheap either. You're better off buying a true HTiB system unless you have the money to start dropping on building your own home
theater setup.

All speaker systems will work, it just depends on the input/outputs available and to figure out which ones to use. I cannot find info on the I/Os for that speaker system. I did find the speaker though. Can you clarify the inputs/outputs on it? I'm assuming
it has a Digital Audio input which in that case is your best bet.
