After doing some more searching I did find this entry in the forum that addressed my issue. #734 (comment) however this is a workaround not a fix so I would suggest that this issue remains open. This workaround can also cause an error if sounds are played to quickly in succession or overlap.

I'm also seeing this when upgrading from 0.16.1 to 0.17.3, #734 (comment) does work (i.e. send MEDIA_PLAYER instead of LOW_LATENCY) but I would like to use LOW_LATENCY on Android.

I'm getting tired that there are so many bugs in this repo. Can anyone recommend alternative solutions for playing sound effects and short mp3 files in Flutter (must work well in iOS)?

Closing this due to reports of this being fixed on newer versions. Feel free to open a new issue in case of this still happening

Does not work on 0.20.1 on Android. Changing to type MediaPlayer works but not what I'd like to have.

Platform android version 31.

I'm not sure if this is worthy of a new issue but: I just saw this issue when testing endless_runner (from https://github.com/flutter/games) on Google Play Games on PC Developer Emulator. After a while, the game started logging this error, not generating any new sounds. Once the current music loop was done, there was silence.

I personally don't plan to fix Android specific bugs, until we have ExoPlayer landed, which again depends on Flutter. We're happy for Pull-Requests though.
