+--- Thread: Audio Mixer Settings from Android (/showthread.php?tid=1838)
Audio Mixer Settings from Android - xalius - 07-24-2016
While looking at the latest Android images, I found a handy XML file that contains mappings from Android audio configs to actual mixer settings (Alsamixer...).
This should help a lot in how to configure audiopaths for different tasks:
Code:
debian@pine64:~/Documents/android_stuff$ cat a64_paths.xml
<mixer>
<!-- These are the initial mixer settings -->
<ctl name="External Speaker Switch" value="1" />
<ctl name="Headphone Switch" value="0" />
<ctl name="Earpiece Switch" value="0" />
<!-- These are commonly used control sequences -->
