**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:

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"
4. Press Start
5. Make some noise

**Expected behavior**
glitch-free audio output

**Actual behavior**
Glitchy audio is output through the system
