Does your headset/mic has a TRRS (Tip, ring, ring, sleeve) connector instead of TRS (Tip, ring, sleeve) connector ?
Yes. It's TRRS.
Does it mean that the headset/mic is a mono mic ?
Is the internal mic mono or stereo ?
I believe it's mono. Based on vumeter activity, and the fact that changing only one slider in hda_analyzer is needed to quiet/mute the mic.
Not sure any difference between cs4206 and cs4207
It seem that you can select ADC1 and ADC2 channel mode in cs4207
‘00’b - ADC2 left channel is mapped to HDA left channel and ADC2 right channel is mapped HDA right channel (normal mode). ‘01’b - ADC2 left channel is mapped to both HDA left and right channels. ADC2 right channel is discarded (mono mode). ‘10’b - ADC2 right channel is mapped to both HDA left and right channels. ADC2 left channel is discarded (alternate mono mode). ‘11’b - ADC2 left channel is mapped to HDA right channel and ADC2 right channel is mapped to HDA left channel (channel swap mode).
