Why is setStreamVolume not working for Vivo Android devices running Android 12?

Question

AudioManager setStreamVolume api is not setting volume for Vivo devices running android 12 and above

I am trying the below code to set the stream volume of the device : Here streamType value is always 0 or 1 as I am using a video call/normal. Here convertedIndex ranges from 1 to 10. Flags i have tried different including AudioManager.STREAM_VOICECALL,AudioManager.STREAM_SYSTEM etc. Right now set as 0 as well. But still volume is not getting set. Made a check for isVolumeFixed before setting. audioManager?.setStreamVolume(streamType, convertedIndex, 0). Apart from setStreamVolume, tried below apis as well : adjustVolume adjustStreamVolume adjustSuggestedStreamVolume setVolumeIndexForAttributes

But none of the apis set volume for Vivo android devices. What could be the possible reason.

Answer 1

you have to modify your system sound settings in developers option and try it again after rebooting the system .
