I used Aux cable, and keyboard port name is Aux In

This is the problem! :)

As you will see from page 30 of the manual here, the Aux in port is when you want to play a song out of the Yamaha PSR E353's speakers:

If you want the sound to come out of the Yamaha, you need to use the PHONES/OUTPUT jack. Again from the manual:

So you need to connect the PHONES/OUTPUT jack to your home theatre system. It looks like the plug is a different size, but if you have something like a 3.5mm Stereo to 6.3mm 1/4-inch Adapter... enter image description here

...you may be able to use the same wire.

    Basic - if a port says 'in' it's for a signal to go 'in'. Same idea with 'out'.
