I’m trying to make audio work in our project without using the legato framework as we have some standard linux programs which needs access to the audio interface. Therefore I have taken some time investigating the codec driver and found out somewhat what settings the amix command is setting and which settings to set to make the codec work for both input and output.
However, i’m currently at a loss for how to unmute the microphone device (seems some of the settings for the audio input is only set on unmute and therefore I need to unmute the device to actually be able to record anything). I therefore thought that I would investigate how legato goes around the unmuting since it obviously work here. But alas I haven’t been able to find a version of pa_audio_default.c which actually store any functionality. Anyone know where to find it, something is obviously compiled to the target, but I cannot identify how?
