| 1371 | * playback to headset+speaker while starting low-lateny usecase for ringtone. |
| 1372 | * So when the ringtone playback is completed, how do we undo the same? |
| 1373 | * |
| 1374 | * We are relying on the out_set_parameters() call on deep-buffer output, |
| 1375 | * once the ringtone playback is ended. |
| 1376 | * NOTE: We should not check if the current devices are same as new devices. |

| 1378 | * playback to headset. |
