Uh-oh, I didn't thought that it will be so complicated to decide when turn one gpio line to 0 or 1 :) Btw, I'm thinking about using own write- and read- wrappers for uda1380, in this way I can check on each read/write whether codec power is enabled.
Are you really cutting all power to the codec or just the analogue supplies? Normally the digital is powered off a separate supply shared with other bits of the system.
Yep, I'm really cutting all power to the codec. AFAIR it saves ~10-15mA of current consumption.
