This question has answers that may be good or bad; the system has marked it active so that they can be reviewed. The device is switched off until pin 3 reaches 0.
As the capacitor charges, it reaches a specific voltage and an internal comparator halts the muting effect.

When power is applied, you could hold pin 3 low for x seconds using a RC circuit or a voltage regulator or voltage supervisor or a microcontroller, enough time for the main voltage to stabilize and for the amplifier to be fully on. I’ve done my research on it but I cant find much.

Luqmaan 18 1 1 5. The capacitor has two behaviors: As to the thump, that requires a sort of logic to make happen.
When the voltage at ttda7262 pin is close to ground, the output is muted. I think they’ve managed to combine these two functions into one by using a capacitor.

You could run an RC filter to the supply voltage to get a power on delay. If pin 3 is connected to at least 0. If pin 3 is disconnected or tdx7262, the amplifier output is disabled.
Doing the same when power is disconnected is much more complicated.
