[Android] Popping/crackling sound occurs when the app is repeatedly brought to the background and foreground while the sound is playing
How to reproduce:
1. Open the “6032.zip“ project
2. Open the “SampleScene“
3. Build and Run for Android
4. In the app press the “PlayOneShot“ button
5. Wait until the app is in the background
6. Switch to some other app
7. Switch back to the original app
8. Repeat steps 6-7 several times while the sound is still playing
Expected result: Once the original app was put back into the foreground there was no speaker crackling/popping noise
Actual result: Once the original app was put back into the foreground there was a speaker crackling/popping noise (it sounds like two big pops going after one other)
Reproducible with: 2023.1.13f1, 6000.0.43f1, 6000.1.0b11, 6000.2.0a7
Not reproducible with: 2022.3.60f1, 2023.1.12f1
Reproducible environment: macOS 15.3.1 (M4 Max)
Not reproducible environment: No other environment tested
Reproducible with these devices:
VLNQA00498, Google Pixel 7 (Pixel 7), Android 13, CPU: Google Tensor G2, GPU: Mali-G710 (most consistent results)
VLNQA00627, Google Pixel 8 (Pixel 8), Android 15, CPU: Google Tensor G3 (GS301), GPU: Mali-G715
VLNQA00518, Google Pixel 4 (Pixel 4), Android 13, CPU: Snapdragon 855 SM8150, GPU: Adreno (TM) 640
VLNQA00335, Samsung Galaxy S20+ 5G (SM-G986B), Android 10, CPU: Exynos 990, GPU: Mali-G77

Not reproducible with:
VLNQA00416, iPhone 13 Pro (MLVA3ET/A), CPU: Apple A15 Bionic, GPU: Apple designed, OS: 16.1.1
Notes:
- You might need to repeat the steps 6-7 several times while the sound is still playing to reproduce the issue
- The repro sound is not the one pop sound that also can be heard when the “Stop“ button is pressed, it is several consecutive pop sounds in a row once the app is in the foreground again
- The crackling is coming from the speakers of the device, so not reproducible with headphones with the AUX connection, and Bluetooth ones

Resolution Note:
After a multiple discussions and thorough investigation, we consider that this is an Android glitch. Closing it this way is acceptable for us because the issue does not prevent the game project from running, and also because this crackling/popping artefact can be expected most of the time when jumping from an app to another.
We acknowledge that something is happening, but doubt that effort to fix this is worthwhile. We did find ways to circumvent this problem by changing focus and lifecycle behaviors, but we are too worried about potential side effects, considering the vast nuances of the Android ecosystem.
