| * Fix AC3 output. |
| * Enable S32_LE format support. |
| * 0.0.10 |
| * Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".) |
| * 0.0.11 |
| * Add Model name recognition. |
| * 0.0.12 |
| * Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period. |
| * Remove redundent "voice" handling. |
| * 0.0.13 |
| * Single trigger call for multi channels. |
| * 0.0.14 |
| * Set limits based on what the sound card hardware can do. |
| * playback periods_min=2, periods_max=8 |
| * capture hw constraints require period_size = n * 64 bytes. |
| * playback hw constraints require period_size = n * 64 bytes. |
| * 0.0.15 |
