For my ears this sounds that the power-down pop is now even worse. I'm
listening with some 32 ohm headphones connected into Beagle.
Before it was kind of sharp snap but now it is snap + low-frequency
tuck/pop. Positive that this low-frequency pop sounds kind of same than
the power-up pop so there is now ramp in both events when coupling
capasitor is charging/discharging.
Do you know is the capacitor coupling configuration correct? TPS65950
is mentioning it but I don't find it at quick look where to configure it
for ac-coupled connection.
