I bought a Blu Ray player that decodes TrueHD and DTS HD. So to take advantage of that, I have analog 5.1 out to my Bryston Sp1.7. I noticed the sub doesnt seem to work in that 5.1 Bypass mode. I read in the manual that there is no bass management in the mode. Does that mean no sub? If so, why would they call it 5.1 bypass.
