A large number of AudioTrack logs

[haroel]

In my NDK project, I integrated SoLoud , and the entire integration process was very smooth. I’m using the OpenSLES backend and successfully played MP3 audio.

However, there are numerous AudioTrack logs continuously being printed. I would like to know how to eliminate these excessive logs?
