    Hi,
    but the nominal of R26 is not written

      Sorry for that, i’d recommend the “R C D” circuit, it is proven to work.

        Yes, but it is does not avoid a pop after shout dawn

          Did you tested it like shown? It actually works fine here on the TPA3132D2 boards. (Even on a hard shut down/power loss)
          Is SDZ connected to FAULTZ?

            Hallo!
            I have 5.1 Amplifier on 4 TPA3116D2, there’s POP problem on shut-down.
            All mute inputs are linked together .
            Does your schematic will work on it?

            P.S. As i figured out in my amplifier combined mute line connected to 10K resistor (on the ground) and non-polar electrolite 2.2uF (i suppose, to VGDD). But this native solution works crappy :(.
