[alsa-devel] how to use DPCM to alter audio path between headphones and speaker

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
