Audio Stuck Partial Wakelock: AudioMix

(I posted this question on the Android forum but then realize that it should better be here)
On Google Play's Android Vitals page, it shows that my game has some Stuck Partial Wake Lock issues with the tag "AudioMix"
As I understand, it means that my game sometimes still plays music even when in background.
Do you know what could be the reason causing this?

Thanks in advance

 

Hi g8minhquan,

We are having a similar issue and have had a number of engineers trying to solve it. It might be best for us to communicate our similarities to see if we can pinpoint a cause ourselves.

I have multiple titles running across Unity 5.6.5 to 2017.4 that are experiencing AudioMix in Vitals. We are near threshold. We have found enormous amounts of resources pointing to AudioFlinger (Androids old audio decoder) being the cause of the lock. What we don't know is what our games are doing to trigger it.

We noticed the growth and spike during our GDPR builds which are using a Native Plugin to display native android assets. No sound though.

Our game is experiencing this most on start-up, or reproduced when the user/tester locks the device on the splash screen/GDPR policy.

We've found similar issues in Cocos caused by EventDispatcher, a fix from Corona SDK that helped other reports, and users attributing it to Lock Sounds on the device. Nothing so far as to why it's caused in Unity, however my assumptions now lead me to believe it was older versions of Unity not having enough support for Android 8.0/8.1 (Which is all Vitals covers and introduces a new Audio decoder) in their audio APIS. So far testing is showing better results of it going away in 2018.1, but unconfirmed.

 

Yes we also have the issue on Android 8.0.0 and 8.1.0
My team is also investigating but haven't found much info
It's strange that my game has most of the issues since beginning of August, and we didn't update the game for quite a long time before that. I guess the issues might come from some 3rd party Ad networks when they have to change to comply with GDPR? Or maybe because Google Play didn't track this issue before that?

 

Have you found a solution yet? Does upgrading to 2018.1 solve the problem?

 

In our case, this issue happen frequently from Aug 6 - Aug 13 and from Aug 28 - Sep 16 (Now).
Beside these days, this issue rarely happen.

 

We are having the same issue, any updates on the matter?

 

We've updated Unity to 2018.2 and the problem seems gone

 

Updating project to 2018.2.20f1 from 2018.1.1f1 has not fixed the issue for me.
Is there any other way to fix that?
Or maybe the problem is in one of SDKs used in my project? (Unity GDPR, Unity Remote settings, Unity IAP 1.21, Appodeal, Photon Network, Google Play Games Services)?

 

We highly suspect that it comes from ads. At least in our cases.
So try to update the ad SDKS, i.e. Appodeal and all the ad network adapters

 

We are having the same issue, has it been solved?

 

We are also having the same issue. Android Console shows my game has some Stuck Partial Wake Lock issues.
Seems unity has a serious problems with sleeping. It could make some marketing issues with your game.
Unity 2018.3.9.

 

Did some digging and apparently the Cocos2d-x developers identified a cause and added a fix in their app java activity.
See this fix:

The thread the lead me to the fix:
https://discuss.cocos2d-x.org/t/audiomix-anr-issue/42867/14


It could easily be the same issue that occurs with unity.
