No audio when it is connected to hdmi or composite cable

rajag, everything here is very confusing.   You say you are running 1.16.13 firmware.   The Live / Live Plus don’t have that firmware (and that’s the section you posted in.)

You also said you downloaded rollback firmware 1.06.15.    That’s for the Live HD (Gen 1), so of course that won’t work if you have a Live Hub or Live Gen3 (SMP.)

Ichigo provided you the manual for the Live Gen 1 / Live Plus, but provided the firmware rollback instruction for the Live Hub / Live Gen 3. 

Which product do you have?  Please reply with the MODEL NUMBER, not a name.
