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).
Do any of the hda tools allow me to tweak this from userspace?
you should ask Takarshi as he added this patch, he may know whether cs4206 support the above feature
