I have just installed z9 with 9 speaker set up - the autocalibration test feeds sound through them but when i play a dvd i get nothing out of the back pair.
NB - The Surround left and right speakers did not originally give any sound either but have turned the levels right up on these and that seems to have fixed it

Re: no sound out of surround back speakers
It sounds like you don't have your surround sound source set up properly (your DVD player is not set up for PCM sound).
the best quality audio will be to set up either digital or optical audio between the DVD and the receiver.
Once you have connected the optical or digital audio cable between the DVD and receiver, you have to go into the DVD player audio setup and change it to PCM digital audio or you will not get surround sound. DVD players are not set up by default to output surround sound.

If everything is connected correct, the only thing I can think of, is you don't put in a surround signal. If you only feed 2 way stereo, only two speaker will work. Also if you switch to stereo, the other channels will stop working. Check the cables, the settings and the input.
LCD will display which speakers are active. And this depends on 2 things: the source signal and decoder mode. If source signal is stereo, only front L+R speakers are used. For 5.1 signal (for example DVD over HDMI / optical/coax spdif) all speakers installed (which are not set to None) are used. To listen to stereo input signal using all speakers, switch decoder to enhancer mode.
surround and subwoofer may not work if there is an additional graphic equaliser operating. 1. check in your receiver speaker setting ensure your speaker setup doesn not have subwoofer set to NONE. this will block any signal to your subwoofer socket. 2 when you select your surround sound setting setup, ensure you select the speaker mode you want, if there is a multicontrol knob, cycle through the choices select subwoofer mode and set it to yes. if you have set-up small speakers S in your speaker settings then it could be that subwoofer is set to yes automatically if you have large speakers L, subwoofer has to be set additionally in the subwoofer setting. 3 test subwoofer on alternative device to test it is working ok consult manual on enjoying surround sound and adjusting the speaker settings.
could be 2 things....
1) The receiver could be set to feed the right speaker with more volume. Check the volume setting for each individual speaker on the receiver.
2) The cable connecting the left input from your dvd player is not connected properly or is bad. Try swapping the left and right audio input cables to see if this moves the problem to the other side. If it does - get a new cable.
all your speaker channels are working so your problem lies with a setup fault. when you watch tv you are only feeding a stereo signal into the amp. you need to select the internal surround sound generator. you need to select either the movie or surround function. the unit will convert the stereo signal to 5.1 channel surround.
After using the method of last resort (RTFM) I discovered that Yamaha 7.1 amps assign an order of priority to the speakers. The surround speakers have higher priority than the surround-back speakers. I had connected the rear speakers (in a 5.1 configuration) to the surround-back speaker terminals and since nothing was connected to the surround terminals the E-6 error happed on auto-setup.
I eventually fixed this by connecting the rear speakers to the Surround L/R terminals and then, via the manual setup menu, set rear surround = NONE. This causes the amp to route the rear-surround signals to the Surround L/R terminals. The auto-configure then completed successfully.
