[alsa-devel] No sound with Sony VAIO VPCZ1 (ALC889)

[Raymond Yau]

>>>
>>> Actually... there should be three mic channels:
>>>     The built-in (internal) microphone
>>>     +
>>>     One mic jack beside the headphone jack
>>>     +
>>>     One other hidden within the headphone jack:
>>>     (a) the Notebook came with Noise-cancelling headsets, but they are
small in-ear plugs so there is no place for noise-cancelling logic in the
plugs
>>>     (b) I think I remember to have read somewhere that this thingy
actually needs the windows driver installed to be noise-cancelling!
>>>     (c) the PLUG of these headphones have another channel (visible
through another ring on the jack)
>>>
>>> This explains the 2nd mic channel :)
>>
>>
>> Try hda-jack-sense-test to find out which node is used by the headset
mic jack (TRRS) and mic jack.

You need root privilege and need 0.20130207 hda-tools
