Here you should have something like: ti,audio-routing = "Ext Spk", "PREDRIVEL", "Ext Spk", "PREDRIVER", "MAINMIC", "Main Mic", "Main Mic", "Mic Bias 1";
So you connect the MicBias1 to Main Mic. When you start playback MicBias1 will be turned on for you.
I tried with this routing (next-20130211 tag kernel). But it is not working for me. So i have gone through other board and found snd_soc_dapm_route for
zoom2.c {"MAINMIC", NULL, "Mic Bias 1"}, {"Mic Bias 1", NULL, "Ext Mic"},
omap3pandora.c {"MAINMIC", NULL, "Mic Bias 1"}, {"Mic Bias 1", NULL, "Mic (internal)"},
But for omap-twl4030.c it is {"MAINMIC", NULL, "Main Mic"}, {"Main Mic", NULL, "Mic Bias 1"},
It Should will be as ? {"MAINMIC", NULL, "Mic Bias 1"}, {"Mic Bias 1", NULL, "Main Mic"},
Because with this i am able to get audio on Devkit8000 as ti,audio-routing = "Ext Spk", "PREDRIVEL", "Ext Spk", "PREDRIVER", "MAINMIC", "Mic Bias 1", "Mic Bias 1", "Main Mic";
In 3.9 this should not work...
linux-next should not have zoom2 at least and I converted the machine drivers as well in regards to micbias handling: e04d6e5 ASoC: twl4030: Convert MICBIAS to SUPPLY widget 57d61b9 ASoC: OMAP: Remove obsolete machine drivers for Zoom2 and SDP3430
