Uh-oh, I didn't thought that it will be so complicated to decide when turn = one=20 gpio line to 0 or 1 :) Btw, I'm thinking about using own write- and read-=20 wrappers for uda1380, in this way I can check on each read/write whether=20 codec power is enabled. > That sounds like something in the teardown path should be done on > startup as well.

Sorry, but what is "teardown path"?
