| |
Hi All,
I am working on Devkit8000 and adding DT support for that. I am trying to add sound DT node support for this boards. I have nearly done with this but facing issue on record. I do not have much knowledge of twl4030 audio codec but with small Hack[1] (as MainMic connected to the input jack) i am able to record sound on Devkit8000. I do not know that MICBIAS1_EN can be enable by amixer commands. Could you please help me to get out of this ?
1) Hack [1]

3) Playback amixer commands amixer set 'PredriveR Mixer AudioR2' on amixer set 'PredriveL Mixer AudioL2' on amixer set PreDriv 100 unmute amixer set 'DAC2 Digital Fine' 100 Thanks, Anil
