seem only support headphone or headset

http://mailman.alsa-project.org/pipermail/alsa-devel/2014-February/072986.html

the two users report thinkpad work well exCelt when dock only

http://support.lenovo.com/en_US/detail.page?DocID=PD029485

Connect headphones or a headset that has a 3.5-mm (0.14-inch), 4-pole plug to the audio connector to listen to the sound from the computer.

Notes:
• If you are using a headset with a function switch, for example, a headset for an iPhone mobile digital device, do not press this switch while using the headset. If you press the switch, the headset microphone will be disabled, and the integrated microphones on the computer will be enabled instead.
The audio connector does not support a conventional microphone.

with headphones the normal headphone 3.5mm with 3-pole without mic is doing the some issues !

the audio is working fine ! maybe because the audio cover the noise

but if I m not playing anything then the static noise is coming out is very low but very annoying !
the only way to stop the static noise is to put in mute mode

the same speaker and headphone with windows is ok !

I don't use any dock station

[pippo (claudio-enjoy)]

discovered that only the right earphone make the noise , on the left is ok

the debug version of the driver show the type of headset , headphone in system log

and headset mic seem use the headphone detection to switch from internal mic to headset mic
