| + <h1>Loop AudioBufferSourceNode, with buffer set after start</h1> |
| + |
| + <p>Test that looping an AudioBufferSource works correctly if the source is started and the |
| + buffer is assigned later, but before the source would start. This can't be easily tested in an |
| + offline context because we can't precisely control when the assignment of the buffer to the |
| + source is done.</p> |
| + |
| + <p>Press the "Start" button for the normal case where the buffer is assigned before start.</p> |
| + |
| + <p>Press the "Start delayed" button for the case where the source is started and the buffer |
| + assigned later.</p> |
| + |
| + <p>You should hear audio about 2 sec after pressing the button. It should continue until you |
| + press the corresponding Stop button.</p> |

| + <button id="Start" disabled onclick='normalStart()'>Start</button> |
