App crashes when attempting to use AAudio on Samsung Galaxy S9

[dturner]

Test device: Samsung Galaxy S9 running Android 8.0.0 G960FXXS2BRI1

Steps to repro:

• Run LoopbackApp
• Change API to AAudio
• Run round-trip latency test a few times

Expected result:

• App runs without crashing

Actual result

• App crashes after running the latency test 2-5 times.

This is probably due to the RefBase bug in AudioFlinger that causes AAudio to crash sometimes on 8.0. Loopback App should disable AAudio on 8.0
