I’ve looked at this thread: 

However, even though my surround speakers are set to full sound, when I play certain things, they simply don’t make any noise.  

Maybe I’m doing something wrong.  But why cant their just be a mode to switch out of surround and simply have all speakers with the same volume and/or have separate control over each speaker.

I think maybe what I would like is having setup profiles, where we could choose on the fly how the speakers work together.

Anyway, any hints.

Just for sample, this site I was trying to play and maybe someone could fill me in why it’s not working.

I’m chromecasting this site through the tv.
 

Thanks,
