I have been looking for addresses for audio and this is what I have so far.
I was able to get beep working fine, I can change volume, type and frequency just fine.
With CONFIG_AUDIO_CONTROLS uncommented
Audio meters working but freeze cam when you record and the meters stop working if you run a beep test.
Audio remote shot works in photo mode, in record mode it will freeze cam once starts to record.
With CONFIG_AUDIO_CONTROLS commented and defining meters and remote shot
Audio meters only work while recording no freeze cam
Audio remote shot works while recording no freeze cam, doesn't work in Photo mode.
Need to try FilterRec fix to see if it helps, pretty sure I found correct address just need to add the code for it to test.
Of course Wav recording does not record anything, it works, just records nothing.
At least meters sort of work and beep works good.
I have been using 600D as Ref and I am pretty sure my stubs are correct, threshold was differ to find but Im guessing it is good since meters are working, seems like something else freezes cam because even if I disable meters it still freezes when I record if I have CONFIG_AUDIO_CONTROLS uncommented.
