Removed comment. Now we continue to return a task

24 // function is called. | |
25 virtual void Stop() = 0; | |
26 | |
27 // Returns the task runner used for audio IO. | |
28 virtual base::SingleThreadTaskRunner* GetTaskRunner() = 0; | |
29 | |
30 // Heavyweight tasks should use GetWorkerTaskRunner() instead of | |
31 // GetTaskRunner(). On most platforms they are the same, but some share the | |
32 // UI loop with the audio IO loop. | |
33 virtual base::SingleThreadTaskRunner* GetWorkerTaskRunner() = 0; | |
