| 425 | * It normally takes about 20-30 msec to start a stream on the server. |
| 426 | * But the first time can take as much as 200-300 msec. The HW |
| 427 | * starts right away so by the time the client gets a chance to write into |
| 428 | * the buffer, it is already in a deep underflow state. That can cause the |
| 429 | * XRunCount to be non-zero, which could lead an app to tune its latency higher. |
| 430 | * To avoid this problem, we set a request for the processing code to start the |
| 431 | * client stream at the same position as the server stream. |
| 432 | * The processing code will then save the current offset |
| 433 | * between client and server and apply that to any position given to the app. |
