^ Good Morning,
My Yamaha AVR does have dedicated 5.1 inputs, and there is a selection on both the AVR and the remote to select "MULTI CH" to use them. There is also another setting in the menu that lets you pick "6ch or 8ch". I selected 8 ch because I have all the 7.1's connected to analog out on the 105. So this is where it gets strange, The Yamaha manual goes on to state "If you selected 8ch in "input channels" (which I did) you can select analog jacks at which Front left & right channels from an external decoder will be input. Choices: CD, CD-R, MD/Tape, BD/HD-DVD, DVD, DTV, Cbl/Sat, DVR, VCR, V-Aux". I selected CD-R because it wasn't currently being used. And that's where I input the dedicated Front L/R outputs (good DAC's) from the 105. I don't see anywhere in the manual that I have to tell the AVR which one of the choices I selected. As an aside, out of those several front channel choices, the manual does have DVD bolded. I didn't use it because my PS3 is connected to that. (I could change that if I needed to but Ithought since 9 other choices, I could pick anyone of them. Since the root of the problem is the front L/R don't have any output in when in 7.1 analog mode, I think that is where my issue is. Do you think I need a "Separate Decoder" separate and apart for the AVR? I hope not..... Bob, I did remove all shiny disc;s from the 105 and ran the test tones, all worked but, you guessed it, the same front left and right main speakers. Another solution for me might be (because I really don't want to buy an "external decoder", as I thought the 105 would act as that)) Is to change the AVR back to 6ch and just use 5.1 channels off the 105 and discard the other two. My main purpose for the analog outs on the 105 is to listen to discrete music such as SACD's and its my understanding, they all have only 5.1 anyway. I know this isn't a Yamaha Z-11 forum and that is where I think my issue is, but any wisdom you gents would like to pass on to me is (as always) greatly appreciated.
