Distorted audio running Android export on Acer Chromebooks

Godot version

3.5.1.stable.official

System information

Acer Chromebook CB5-132T

Issue description

Audio playback is very distorted sounding when running an Android apk exported with Godot 3.5.1 on an Acer Chromebook CB5-132T. Our users have also reported distorted sound on Acer Chromebooks CB3-431 and CB3-532

The problem did not reproduce on a Dell Chromebook 5190

Audio also sounds fine when exported with Godot 3.4.5. I was unable to test on 4.0 due to another error (Unable to setup the Godot Engine! Aborting.)

I also tested converting the ogg to wav and it still sounded bad.

Steps to reproduce

1. Create New Project
2. Create User Interface Scene
3. Add AudioStreamPlayer
4. Add a ogg file to project (I used House In a Forest Loop.ogg from https://docs.godotengine.org/en/stable/_downloads/923b18d4e18125cf494ee5f7efba7e03/dodge_assets.zip)
5. Drag ogg to AudioStreamPlayer
6. Check on Playing and Autoplay
7. Export Android APK
8. Install APK on Acer Chromebook and run

I narrowed it down to a change in Godot 3.5 rc5
The change is in commit: Upgrade Android NDK to r23 LTS 061c280

It wasn't the upgrade to NDK r23 though. It's something else, I suspect switching from mingw to clang. I determined this by reverting the above commit, and then setting the ndkVersion back to '23.2.8568313'

This fixed the audio for us on our Acer Chromebook.
