James Courtier-Dutton | 22bc30c | 2005-05-07 16:13:40 +0200 | [diff] [blame] | 4 | * Version: 0.25 |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 5 | * |
| 6 | * FEATURES currently supported: |
| 7 | * Output fixed at S32_LE, 2 channel to hw:0,0 |
| 8 | * Rates: 44.1, 48, 96, 192. |
| 9 | * |
| 10 | * Changelog: |
| 11 | * 0.8 |
| 12 | * Use separate card based buffer for periods table. |
| 13 | * 0.9 |
| 14 | * Use 2 channel output streams instead of 8 channel. |
| 15 | * (8 channel output streams might be good for ASIO type output) |
| 16 | * Corrected speaker output, so Front -> Front etc. |
| 17 | * 0.10 |
| 18 | * Fixed missed interrupts. |
| 19 | * 0.11 |
| 20 | * Add Sound card model number and names. |
| 21 | * Add Analog volume controls. |
| 22 | * 0.12 |
| 23 | * Corrected playback interrupts. Now interrupt per period, instead of half period. |
| 24 | * 0.13 |
| 25 | * Use single trigger for multichannel. |
| 26 | * 0.14 |
| 27 | * Mic capture now works at fixed: S32_LE, 96000Hz, Stereo. |
| 28 | * 0.15 |
| 29 | * Force buffer_size / period_size == INTEGER. |
| 30 | * 0.16 |
| 31 | * Update p16v.c to work with changed alsa api. |
| 32 | * 0.17 |
| 33 | * Update p16v.c to work with changed alsa api. Removed boot_devs. |
| 34 | * 0.18 |
| 35 | * Merging with snd-emu10k1 driver. |
| 36 | * 0.19 |
| 37 | * One stereo channel at 24bit now works. |
| 38 | * 0.20 |
| 39 | * Added better register defines. |
| 40 | * 0.21 |
| 41 | * Integrated with snd-emu10k1 driver. |
| 42 | * 0.22 |
| 43 | * Removed #if 0 ... #endif |
James Courtier-Dutton | f927c8f | 2005-05-07 15:34:13 +0200 | [diff] [blame] | 44 | * 0.23 |
| 45 | * Implement different capture rates. |
| 46 | * 0.24 |
| 47 | * Implement different capture source channels. |
| 48 | * e.g. When HD Capture source is set to SPDIF, |
| 49 | * setting HD Capture channel to 0 captures from CDROM digital input. |
| 50 | * setting HD Capture channel to 1 captures from SPDIF in. |
James Courtier-Dutton | 22bc30c | 2005-05-07 16:13:40 +0200 | [diff] [blame] | 51 | * 0.25 |
| 52 | * Include capture buffer sizes. |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 53 | * |
| 54 | * BUGS: |
| 55 | * Some stability problems when unloading the snd-p16v kernel module. |
| 56 | * -- |
| 57 | * |
| 58 | * TODO: |
| 59 | * SPDIF out. |
| 60 | * Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz. |
| 61 | * Currently capture fixed at 48000Hz. |
