Digital MIC on VAR-DT6CustomBoard [ANSWERED]

Postby sammyp » Mon Nov 02, 2015 9:02 am

Hello,

Where can I find documentation on how to get the digital microphone working on the VAR-DT6CustomBoard? For the TLV320AIC3106 codec, it seems that only analog I/O is available through tinyalsa. Is it possible to change the codec routing to enable DMIC using a different devicetree?

If my understanding is correct, the codec generates an audio clock on GPIO1 and the PCM signal is connected via GPIO2, but it seems the default settings disable this functionality.

Please see a patch, to replace the original line-in with the DMIC one. (rename to .patch)
