Were you ever able to resolve this? We’re seeing the same thing on a non-unity game, call-stack below.

Again, a full log would be helpful here as I cannot see “fmod” anywhere in this call stack. You can enable error logging by using the fmodL and fmodstudioL libs and calling [`Debug_Initialize`](https://fmod.com/resources/documentation-api?version=2.02&page=core-api-common.html#debug_initialize) with `FMOD_DEBUG_LEVEL_LOG` as the first argument. ---

We integrated the latest FMOD Core Engine ourselves instead of using the FMOD for Unity. All audio-related code was written in C++, and on the Unity C# side, there are only wrapper functions for P/Invokes. No Unity Audio API calls and Unity Audio Listeners at all. In the Audio settings, the “Disable Unity Audio” option was ticked. But the “Visualize Effects” option was on. (This wasn’t intentional. I turned this off after this writing.) All other options including the “Global Volume” were set to 0, 1, “Mono”, and “Best latency”. We initialize the FMOD system manually either with **AAudio** or **OpenSL**. Not using **Auto** or **AudioTrack**. NEVER. But one of our users is experiencing an **AudioTrack** error, not always, but very often. Below is all the backtrace after the crash: > backtrace: > #00 pc \*\*\*\* /system/lib64/libaudioclient.so (android::AudioTrack::setVolume(float, float)+512) (BuildId: \*\*\*) > > at libaudioclient.android::AudioTrack::setVolume(float, float)(setVolume:512) I don’t get this. Does FMOD utilize **AudioTrack** under the hood even when it is set to **AAudio**? This user’s phone is Redmi Note 10 Pro (Android 12), and reading the above comments, it seems like this issue has something to do with Redmi and Xiaomi phones. (We had no issues at all with other devices so far.) Any thoughts/guesses on this issue? ---

> [@jiyongman](#): > > Does FMOD utilize **AudioTrack** under the hood even when it is set to **AAudio**? FMOD does not use AudioTrack internally for the AAudio and OpenSL output types. I’m assuming it isn’t feasible for you to [Enable API Error Logging](https://fmod.com/resources/documentation-unity?version=2.02&page=settings.html#enable-api-error-logging) and get a full log from your user? > [@jiyongman](#): > > This user’s phone is Redmi Note 10 Pro (Android 12), and reading the above comments, it seems like this issue has something to do with Redmi and Xiaomi phones. We have had reports of crashing when the volume is muted on modern Huawei and Xiaomi devices, which might explain why the issue is reproducing irregularly on your user’s device. Unfortunately we cannot acquire any of the devices that this issue has been reproducing on in our country. If you are in contact with your user you could potentially get them to check whether the issue reproduces if the volume is muted/unmuted? ---

The user suddenly stopped responding, so there’s no more information we can get. But thanks for letting us know about the volume issue. We will ask about that when another user experiences the same crash. ---

We still haven’t been able to reproduce this crash. Can you please tick _[Enable API Error Logging](https://fmod.com/docs/2.02/unity/settings.html#enable-api-error-logging)_ , set your _[Logging Level](https://fmod.com/docs/2.02/unity/settings.html#logging-level)_ to “Log”, and post the output of your game’s log here up to when the crash occurs? ---

This can be related to the modification in audio subsystem of miui/huawei. Using screen recorder in app using fmod on these devices will cause no sound or random noise. You may change OutputType to opensl instead of aaudio, which is default. Hope this helps. ---

hi jeff, as far as i know, on miui with screen recorder running, app will easily crash with such backtrace. it’s probably not the bug of fmod, because wwise has same problem 😆(genshin impact introduced an audio compatible mode in v1.5 to avoid this). i think there is something wrong with fmod working on miui/huawei aaudio subsystem, but it is difficult for me to debug fmod or android system in lowlevel. i hope you guys can conduct a deep investigation on it. ---

This seems to be a [bug with the Google Oboe API](https://github.com/google/oboe/issues/538). We aren’t using Oboe, but there appears to be other apps running in the background on these devices that are- the screen recording app is likely an example of this. There is a fix scheduled for Android T which came out August 15 2022, so hopefully this crash will start disappearing as more people move to the latest Android OS. ---

What version of Android was on the device? > [@jeff\_fmod](#): > > This seems to be a [bug with the Google Oboe API](https://github.com/google/oboe/issues/538). We aren’t using Oboe, but there appears to be other apps running in the background on these devices that are- the screen recording app is likely an example of this. > There is a fix scheduled for Android T which came out August 15 2022, so hopefully this crash will start disappearing as more people move to the latest Android OS.
