32 | * Set limits based on what the sound card hardware can do. | |
33 | * playback periods_min=2, periods_max=8 | |
34 | * capture hw constraints require period_size = n * 64 bytes. | |
35 | * playback hw constraints require period_size = n * 64 bytes. | |
36 | * 0.0.15 | |
37 | * Separate ca0106.c into separate functional .c files. | |
38 | * 0.0.16 | |
39 | * Modified Copyright message. | |
40 | * 0.0.17 | |
