Here is my DAPM_DEBUG traces : 
Please notice that for some internal reasons, this driver is not at all the
same as wolfson release ;)

I initialize FM Transmitter like this : 
	snd_soc_dapm_set_endpoint(codec, "FM Transmitter", 0);
but it still enabled. Why ?
Do you have any ideas on why both HP and FMOUT PGAs are powered ?

Thanks.

Alex.
