This patch fixes the - agressive - 'tuck' sound heard when the codec goes to standby mode.
We need to wait for the ramp down completion in case of headsetl_event:POST_PMD.
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.
