How to connect DTH, Sony Bravia and Intex 5in1 speakers

Hi,

I have connected Sony TV, Sun DTH, Onida DVD player with Intex 5in1 speakers to get good sound through 5in1 speakers for both DTH and DVD Player.

Got good sound if I use DVD player/USB.

If I switch on TV, I am able to sound from sub woofer and 2 speakers only(front and rear), not from other 3 speakers.

Can you please help me in getting sound in all 5 speakers+woofer when I switch on TV.

Regards
Sri
