Thanks for reply, I read Datasheet, Mute & Standby works similarly, If not connected = Mute/Standby OFF. I wish to build with NO Popping. I don't know what affects Mute/Standby to POP.

There are some other components you can add, check the optional component section.

A small ceramic cap across the input wires might help.

Edit not much on that sheet, wait for more advise or look at the LM3875 datasheet for some ideas.

While googling I found most of the schematic skipped mute/standby pins.

Yes.

I was going to suggest skipping the mute unless you need it.

To eliminate POP I purchased LM1876, otherwise I would have used LM1875.
