| * Driver p16v chips |
| * Version: 0.21 |
| * |
| * FEATURES currently supported: |
| * Output fixed at S32_LE, 2 channel to hw:0,0 |
| * Rates: 44.1, 48, 96, 192. |
| * |
| * Changelog: |
| * 0.8 |
| * Use separate card based buffer for periods table. |
| * 0.9 |
| * Use 2 channel output streams instead of 8 channel. |
| * (8 channel output streams might be good for ASIO type output) |
| * Corrected speaker output, so Front -> Front etc. |
| * 0.10 |
| * Fixed missed interrupts. |
| * 0.11 |
| * Add Sound card model number and names. |
| * Add Analog volume controls. |
| * 0.12 |
| * Corrected playback interrupts. Now interrupt per period, instead of half period. |
| * 0.13 |
| * Use single trigger for multichannel. |
| * 0.14 |
| * Mic capture now works at fixed: S32_LE, 96000Hz, Stereo. |
| * 0.15 |
| * Force buffer_size / period_size == INTEGER. |
| * 0.16 |
| * Update p16v.c to work with changed alsa api. |
| * 0.17 |
| * Update p16v.c to work with changed alsa api. Removed boot_devs. |
| * 0.18 |
| * Merging with snd-emu10k1 driver. |
| * 0.19 |
| * One stereo channel at 24bit now works. |
| * 0.20 |
| * Added better register defines. |
| * 0.21 |
| * Split from p16v.c |
| * |
| * |
| * BUGS: |
| * Some stability problems when unloading the snd-p16v kernel module. |
| * -- |
| * |
| * TODO: |
| * SPDIF out. |
| * Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz. |
| * Currently capture fixed at 48000Hz. |
