Greetings,
I'm working with a board that has a TI TLV320AIC3105 codec connected
to an IMX6 SSI with a headphone jack and a TS3A227E headphone detect
chip (HPROUT/HPLOUT), mono speaker amp output (RIGHT_LOP/RIGHT_LOM),
and mic in (MIC1L). It seems that Dynamic PCM allows for the automatic
routing of audio to change between headphone out and speaker out
depending on jack insertion/removal event but I'm not clear how to
configure that. Can this be done via simple-audio-card bindings or
does it require a modified machine driver?
Any pointers or references are greatly appreciated!
Best Regards,
Tim
