Good afternoon,
I was wondering if anyone had a clue what the following devices concretely relates to in etc/audio_policy.conf
I can guess a little but would like more information if anyone has a clue. Also, please correct me if I'm wrong.
Long story short, I'm on the hunt for the FM_in and LINE_in, unmute, and play all of them through LINE_OUT
I managed to find the file reading this post, https://www.olimex.com/forum/index.php?topic=3645.0, not the same file, but I remember playing with this before, so at least I'll have line out working with HDMI shortly, if I can find the right dog damn file to edit... my memory is lacking atm. I remember an IF statement somewhere for HDMI switch, but the where... no clue.
Input devices:
AUDIO_DEVICE_IN_BUILTIN_MIC - Self explanatory perhaps, microphone port on Olinuxino-a20
AUDIO_DEVICE_IN_WIRED_HEADSET - Sounds like Line in to me (pun intended :P)
AUDIO_DEVICE_IN_BACK_MIC - Mic 2 ?
AUDIO_DEVICE_IN_AF - Could this be FM_IN ?
Thanks in advance.

PS: anyone has any info that could help me with audio... post please
Wow that took hours...
easy way to switch between digital out (HDMI or spdif, spdif has priority over HDMI) and analog out:
Set analog: setprop audio.routing 2
Set digital: setprop audio.routing 1024
Tested working.
for future reference...
