i understand your issue.
Last time some one manipulated the TDA2822 adopting 7806 regulator.
Perhaps in files ot photos section you find the details of back plane as I saw the regulator was mounted on reverse.
The power line leading to pin2 is entering up to middle of chip on bottom side and with a through hole, it is to top layer and reaching pin 2
i shall also search and link the photos for your need.

Dear OM Sharmaji,
Thanks for your reply. Yes, Farhan has not published the PCB overlay. It's difficult to find the tracks in a SMD populated board. If you are using it, can you tell me how the audio IC 's pin 2( VCC) is connected to 12 V on the PCB?
