Hello, we have a problem using FMOD Android SDK (2.02.27) on Android 6(API Level 23) emulator platform. Other Android versions work fine (tested 22, 24 and above).
I’ve modified your simple_event example. You have to add a line
ERRCHECK( coreSystem->setOutput(FMOD_OUTPUTTYPE_OPENSL) );
to reproduce it. If you change it to
ERRCHECK( coreSystem->setOutput(FMOD_OUTPUTTYPE_AUDIOTRACK) );
everythnig works fine then.
Your docs says that FMOD_OUTPUTTYPE_OPENSL should be default for this Android version, but it seems it doesn’t, because without setting the output the bug doesn’t appear.
Here are logs:

I can reproduce this in the emulator as described, thank you for reporting this issue. I can’t immediately see what the problem is, I will pass it onto the Dev team to investigate further.
Have you fixed this problem? I don’t see any fixes in the release change log…
We reproduced this issue outside of FMOD, and I’ve filed a bug report with the Google Oboe API 44.1kHz sample rate silent on emulated Android 23 device · Issue #2232 · google/oboe · GitHub
It appears that for whatever reason, OpenSL doesn’t work with 44.1kHz on an emulated Android 23 device, with or without FMOD. If I switch our OpenSL implementation to use 48kHz it works on the emulated device without issue, and the task now is to explore options for changing the OpenSL sample rate. I will bump the task.
I’ve tried to use your fix with setSoftwareFormat and various values like 48000 and 24000, but there is still no sound at all. The only thing that works is to change setOutput to FMOD_OUTPUTTYPE_AUDIOTRACK.
