Audio in Android build is much quieter than in Windows build

I recently finished my game and released it on Windows and WebGL and now I’m trying to port my game to Android but I’m running into an issue where the audio is super quiet.

It’s only on the Android build that this happens, and the audio is VERY quiet. I usually keep my phone at about 20% volume, which sounds perfectly audible for most applications, but I have to turn my phone volume all the way to 100% to get a comparable audio level out of my game.

My phone is a Google Pixel 3 which I know is pretty old, but it doesn’t have audio problems with anything else (in fact the reason I’ve kept it so long is because the speakers are great), so I’m 99% certain this is a Unity problem, specifically with building to Android because my game sounds wonderful in the Windows build, and WebGL build, and in editor with the current settings.

I’ve tried maximizing the volume of my audio sources and maximizing my volume mixers to +20 DB, as well as amplifying the raw audio file in Audacity, and now the sounds are a bit louder (not nearly as much as I would have expected) but they are low quality, have clipping issues, and don’t sound like the PC build at all. Is there any way to increase the volume of my android build in a way that doesn’t sacrifice audio quality?

Hi @LummieThief,

Would you be able to try on different phones? Different generations of Android OS might use different audio backend, so it would be helpful in discriminating this.

After that, I suggest you open a bug report on this matter. Any additional info helps:

  • Models of phone tried
  • Android version on these phones
  • Audio/video footage of the issue
  • Sample project

Thank you
