Hi,
when the AC is off , there is POP sound. We added the mute control circuit, but whenever we put /CMUTE low, the POP sound would come out. There are two problems:
1. Why does /CMUTE turn low to make POP sound?
2. How to solve the POP sound when AC is off?
the AC off Mute circuit：
the /CMUTE is pulled low ,POP sound come out wave
2. Zoom in the POP around
3.Push /CMUTE directly to the ground with a touch of the switch, and you can see that /CMUTE pulls down while making a POP sound:
