PixiJS Sound v4.4.1 has a pause/resume issue when working with spritemaps. Pausing and resuming a sound causes unexpected behavior, such as jumping to the next sound in the spritemap instead of restarting the current sound.
I believe that this issue arises because the internal _elapsed time scales according to the entire spritemap, and the AudioBufferSourceNode API lacks native pause/resume functionality. The known workaround is to manually control the playbackRate property of the AudioBufferSourceNode.
It has a detailed description of the issue, the use-case applied, and a an option to test the workaround as a well a fix for the elapsed time.
In the repro repository, the WebAudioNode instance is used to toggle paused state. I'm not 100% sure that this is an intended way. When you run the repro project, open it in your browser and follow the instructions to experience the problem.
