--- Comment #4 from TomG <tom at pixeltom.net> ---
We've also discovered this behaviour on iOS15 devices.

Using this WebAudio example: https://mdn.github.io/webaudio-examples/audiocontext-states/ 

After creating the context, we've had some of our devices have sound cut off at 6 seconds, some at 30 seconds. But the time display below is always faster than what it should be. Once it gets a few seconds ahead of what it should be (about 2), it cuts off. Suspending and renewing does nothing for the audio. The context needs to be killed and then recreated. But then it happens all over again.

One interesting thing to note. We only experience that behaviour remotely. If we run the same code for the test above in a local server, we have no problem. The context time ticks along at the correct speed.
