Glitching while using Oboe Tester's "Echo Input to Output" - Pixel 6 with Pixel Buds

[MarkoGill]

Android version(s): 12 Android device(s): Pixel 6 with Pixel Buds connected Oboe version: Oboe v 1.6.2 App name used for testing: Oboe Tester (57) v 2.2.3

Short description The Pixel 6 is glitching when using the Echo test with Bluetooth headphones connected.

This behavior is inconsistent. It will exhibit one of 3 behaviors:

1. Report xRuns in the "xRun#" log, and experience glitches
2. Not report any xRuns, and experience glitches
3. Not experience glitches

It does not experience any glitching when using Record And Play.

Steps to reproduce

1. Select "Echo Input to Output"
2. Press Start
3. Make some noise

Expected behavior glitch-free audio output

Actual behavior Glitchy audio is output through the system

Any additional context The same behavior is present in Smule.

Thanks for the report! I can repro the glitches on Android 12.1 sometimes.

I cannot seem to repro this on Android 13.

I replicated it on Android 14 (Pixel7) on Oboe Tester (78) v2.3.7 Oboe v1.8.0. On my OnePlus6 using Android 11 and Oboe((66) v2.37, Oboe v1.7.2 it doesn't happen.
