Hi guys, I just acquired this Onkyo TX-SV909PRO AV amp, I hooked up with a 5.1 system with a dvd player.

My question is when I  turned on the surround mode there is no audio producin in any of my 5 speakers.

What am I missing here? Each of the surround mode I selected dosent seem to work.

As I do not have the original manual and remote control I do not know what are other setup options.

Only when I turned off the surround mode I only get the audio through my front 2 speakers which is normal right?.

I know its a old amp but if you guys have ever owned or experienced with this amp before please tell me what are the proper steps

to  turn on the surround mode. I'll appreicate any of your reply, thanks.
