Audio cuts out when CPU under load

I am using the sample app to play audio in the background but when I do anything CPU intensive like open another app or even just scrolling through the list of apps on my phone the audio cuts out and then resumes once the redraw or other CPU intensive operation has finished. Is there any way to avoid this and have the audio streaming smoothly while other operations are happening on the phone?

Start by reproducing the sample app's background audio playback while opening another app or scrolling under CPU load; inspect the Android playback path and the sample-app entry point. Done means audio continues smoothly during those operations, with normal playback still working.
