The "Headset Mic 2" and the "Headset Stereophone" widget are managed by the jack detection logic. Their will be set depending on whether something is connected to the jack or not. There is no need to manually change the state beforehand as it will be overwritten anyway. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
