TPA3123D2 getting warm at startup

Dear All,

                 I had build a double sided proto-board in reference with Ti's TPA3123D2-EVM board. My problem is that when ever I am trying it out with linear power supply it is working but when I am trying it out with wall-adaptar o/p or smps its getting hot at no-load,no signal condition . Shutdown,Mute voltages are OK , even the output is at half-supply but the IC is getting hot & no output is coming out.

But the EVM is working with both of supplies. Any suggestion??

I can post the Layout in pdf if required.
