29 *  0.0.13
30 *    Single trigger call for multi channels.
31 *  0.0.14
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 *    Separated ca0106.c into separate functional .c files.
38 *  0.0.16
