| 30 | * 0.0.13 |
| 31 | * Single trigger call for multi channels. |
| 32 | * 0.0.14 |
| 33 | * Set limits based on what the sound card hardware can do. |
| 34 | * playback periods_min=2, periods_max=8 |
| 35 | * capture hw constraints require period_size = n * 64 bytes. |
| 36 | * playback hw constraints require period_size = n * 64 bytes. |
| 37 | * 0.0.15 |
| 38 | * Separated ca0106.c into separate functional .c files. |
