No, the bug happens when you assign only two front speakers to your AVR configuration. Let's say you only have two physical speakers and that is your configuration in an AVR. Then you have rising noise and distortion (not sure if both, but one for sure).
But if, still having only two speakers, you assign all the 11 speakers in an AVR, even though you don't physically connect them, then you will not have the bug. You can still play 2ch content fine, but in that case it would be hard to downmix mch content to 2ch, if not impossible. Of course, it is better to connect all the speakers you have.
So the problem that remains is if you want to play mch content on two speaker configuration. But, why would you do that??? Then go buy stereo integrated amp.[/QUOT
Thank you for your explanation. The reason I need to know about 2 channel is about 20% of the time I listen to the RL channels for stereo music off of my AVR. I dont have enough rooms to have seperate systems, so I use the living/dining room for HT and stereo listening. I guess I'm after the best of both worlds, without breaking the bank.
