You could run an RC filter to the supply voltage to get a power on delay.

If pin 3 is disconnected or grounded, the amplifier output is disabled.
If pin tea7262 is connected to at least 0. You can mute it again by just discharging the capacitor with a transistor switch, I think.
Doing the same when power is disconnected is much more complicated.
This is used for sensitive applications or circuit’s Where a brown yda7262 voltage behavior is unwelcomed. When the voltage at the pin is close to ground, the output is muted. This question has answers that may be good or bad; the system has marked it active so that they can be reviewed. I think they’ve managed to combine these two functions into one by using a capacitor. The device is switched off until pin 3 reaches 0. Sign up or log in Sign up using Google.
When power is applied, you could hold pin 3 low for x seconds using a RC circuit or a voltage tad7262 or voltage supervisor or a microcontroller, enough time for the main voltage to stabilize and for the amplifier to be fully on.
It’s not the same IC but the function is similar.
As to the thump, that requires a sort of logic to make happen. You can check TDA for a more thorough explanation on how it is supposed to work. As the capacitor charges, it reaches a specific voltage and an internal comparator halts the muting effect.
