[Issue]: Some bluetooth earphone will very lag on a not support AAudio system

[leoxxx]

Describe the bug

I test it on Android 4.4.4, 7.1.1 and 9. It will very lag on 4.4.4 & 7.1.1, 9 is O.K. I test the bluetooth earphone on other emulators (e.g. myboy, ppsspp), not very lag on a not support AAudio system.
AAudio: Android 8 and later.

Steps to reproduce

Use bluetooth earphone on not support AAudio system.

Expected behavior

Lag the same as support AAudio system.

Then change your emu audio driver to OpenSL if your headset's not support it (?)

No option to change audio drive before Android 8 in emu.
