Hi,
I'm currently working on a beagle board clone.
I've got some problems getting the micbias1 output on the TPS65950 to work. I can record audio coming from a line out or if I connect micbias1 to an extern 1.8V supply.
/sys/devices/platform/soc-audio/TWL4030/dapm_widget shows Mic Bias 1 to be off at all times. Is there something I have to do to enable this other than to start recording? Or could this be a bug in the driver? Does anyone have experience with the mic input of the TPS65950?
Thanks, Maximilian
