DAPM WM8900 snd_soc_dapm_stream_event FM Transmitter: On in 2 out 1 in static FMOUT_R in static FMOUT_L

I initialize FM Transmitter like this : snd_soc_dapm_set_endpoint(codec, "FM Transmitter", 0); but it still enabled. Why ?

According to the above trace your FM transmitter is still reporting as being connected. Have you checked to ensure that your your call to configure the transmitter is happening after your board widgets have been registered?
