Bluetooth audio issue on android about mobile HOT 4 OPEN

I can provide some feedback here, maybe try to revive this issue a little bit. Using Airpods pro 2 on Android, Bluetooth delay is consistently around 300ms (0.3 of a second).
However the piece's sound delay ranges from half a second to sometimes multiple seconds. This inconsistency in timing leads me to believe that the majority of this delay stems from the app itself.

I was able to get this delay on video with a screen capturer. Because of the inconsistent timings of piece sounds, I'll share a few moments of long delays, and shorter delays.

Here's a long delay: these only happen occasionally, maybe 5% of the time.

Here's a medium delay, these happen frequently, yet sporadically:

Finally, here are some examples where delay isn't really present:

All of these examples were taken from the same game while using Airpods pro 2 on Android 14.

To add to this, I have noticed the same trend, where the longer the interval between when a move was last played and the next move, the larger the delay heard. The large delay, as shown above, was played after 11 seconds of thinking.

If it's coming from the app, no idea where it comes from. But this where to look at: https://github.com/lichess-org/flutter-soundpool

Two ideas that I saw there were sound cache issues, and Bluetooth going into a low power state, and having to wake up, causing a delay.
I was able to replicate the delay by waiting around 15 seconds before making a move. The longer I waited the more delay I could get.
