Android: Device build_output_stream eventually stops working.

[erikas-taroza]

While testing on Android, I ran into an issue with calling build_output_stream. In my project, I use symphonia to decode audio files and cpal to produce sound. Every time I played a new file, I would call build_output_stream.

This would stop working after 40 calls of the method. This error is thrown.

I have created a workaround fix where I call build_output_stream only once. However, I am concerned with the StreamConfig changing between audio files. Is there anything that can be done in cpal to fix this issue?

I have created a project that reproduces this issue and I have included the workaround I made. You will need cargo-apk installed to run it.

This issue is fixed in oboe-rs but the changes have to be merged. For now, I created this fork that uses the fix:
