Test plugging in/unplugging headphones on A51 whilst running Oboe app

Use Shruti app.

If we get crash or ANR take a bug report.

Test steps:

• Install Shruti Carnatic Tuner app from Google Play
• Run app and tap on "Sa" to hear a tone
• Insert headphones, listen for output on headphones, remove headphones, listen for output on built-in speaker

I tried plugging in and unplugging headphones in both the 3.5mm jack and the USB-C socket (via a Pixel USB headphone dongle). For both connection methods I tried rapidly plugging in and unplugging the headphones. As an estimate I did it about 50 times.

I did not receive any crashes or ANRs.

The only peculiarity I did notice was that with the USB-C connection the audio would often not switch over to the headphones, it just stayed on the built-in speaker - like the stream was not disconnected.
