https://foobar404.github.io/Wave.js/#/ does not output any audio when the GPUProcess is enabled (works fine with GPUProcess disabled).

Comment 2 Chris Dumez 2021-01-21 09:39:00 PST 
Event though the media file starts playing in the GPUProcess, its current time never changes (stays 0). The media is definitely in PLAYING state, not paused.

Interestingly, bypassing RemoteMediaPlayerProxy::setShouldEnableAudioSourceProvider() seems to unblock media playback as I see the current time changing. It must be an issue with the provider somehow.

This is due to sandboxing. Fixing now.
