I agree this does seem to be related to performance, and HTML5 is notorious for performance issues due to its lack of threading support. Increasing the DSP buffer size is a good start, you could also try changing the [Loading Mode](https://fmod.com/docs/2.02/studio/managing-assets.html#loading-modes) of any streaming assets to Compressed or Decompressed.  
For best performance on HTML5 you can try enabling [SharedArrayBuffer](https://web.dev/cross-origin-isolation-guide/), which can be set from the server header with `Cross-Origin-Opener-Policy: same-origin` and `Cross-Origin-Embedder-Policy: require-corp` policies.
