[Galaxy S 4 i9505 Original Android Development] nortexxx:
Thanks for the first help - But nothing really worked so far...i googled a lot - found some tutorials and made this:

I have opened the build.prop and have the following I can change:

# Audio

audio.offload.disable=1

persist.audio.fluence.speaker=true

persist.audio.fluence.voicecall=true

qcom.hw.aac.encoder=true

ro.qc.sdk.audio.fluencetype=fluence

use.dedicated.device.for.voip=true

use.voice.path.for.pcm.voip=false

I changed "ro.qc.sdk.audio.fluencetype=fluence" to "none" .... made nothing better :(

-- Is there another thing I am able to change to make it better? or to add?

I have also found the system/etc/mixer_path.xml which contains the following:

<?xml version="1.0" encoding="ISO-8859-1"?>
