Hello,
The following patch should fix (or at least makes it less intrusive) the 'tuck' phenomena on observed on the twl4030 Headset outputs when the codec is going to standby mode.
I have debugged this with the scope and if we are not waiting RAMP_DELAY time, the VMID is cut before it reaching 0, which generates the 'tuck'.
Note that I have not removed the control for the RAMP_DELAY configuration, the code will use that to calculate the needed delay (also the sysfreq is needed, which also stored). However I do think that one should not touch the RAMP_DELAY...
It would be nice to hear from you guys, if it solves/softens the 'tuck'.
