Yamaha HTR-6030: all speaker have sound coming out but it is not true surround. The display only shows front speakers on, how do I get all speakers to come up on the display?

The surround system you have has two speaker options which allow you to run two sets of speakers. When I had one, one set (A) was used for surround sound, and set (B) by for speakers through out the rest of the house. I am going off memory, but there is a setting to add the rest of the speakers (Note that if one rear speaker has a bad connection), it will not allow you to use any of them). Make sure all your speakers for the surround are set up to (A) speakers (Do not use B speakers until you have your surround working), then use the shift and test button to check each speaker, you will hear static for the test. Note that the surround modes on this unit are not all standard, so I would highly recommend using an optical toss link cable. Also make sure you have an audio source that is outputting surround sound, and select the correct input. G-luck.

I think you mean the display only shows Front >>Channels<< available.

What source? Digital or analog (analog is only stereo).
