Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 5 | * |
| 6 | * FEATURES currently supported: |
| 7 | * Front, Rear and Center/LFE. |
| 8 | * Surround40 and Surround51. |
| 9 | * Capture from MIC an LINE IN input. |
| 10 | * SPDIF digital playback of PCM stereo and AC3/DTS works. |
| 11 | * (One can use a standard mono mini-jack to one RCA plugs cable. |
| 12 | * or one can use a standard stereo mini-jack to two RCA plugs cable. |
| 13 | * Plug one of the RCA plugs into the Coax input of the external decoder/receiver.) |
| 14 | * ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. ) |
| 15 | * Notes on how to capture sound: |
| 16 | * The AC97 is used in the PLAYBACK direction. |
| 17 | * The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC. |
| 18 | * So, to record from the MIC, set the MIC Playback volume to max, |
| 19 | * unmute the MIC and turn up the MASTER Playback volume. |
| 20 | * So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume. |
| 21 | * |
| 22 | * The only playback controls that currently do anything are: - |
| 23 | * Analog Front |
| 24 | * Analog Rear |
| 25 | * Analog Center/LFE |
| 26 | * SPDIF Front |
| 27 | * SPDIF Rear |
| 28 | * SPDIF Center/LFE |
| 29 | * |
| 30 | * For capture from Mic in or Line in. |
| 31 | * Digital/Analog ( switch must be in Analog mode for CAPTURE. ) |
| 32 | * |
| 33 | * CAPTURE feedback into PLAYBACK |
| 34 | * |
| 35 | * Changelog: |
| 36 | * Support interrupts per period. |
| 37 | * Removed noise from Center/LFE channel when in Analog mode. |
| 38 | * Rename and remove mixer controls. |
| 39 | * 0.0.6 |

| 60 | * capture hw constraints require period_size = n * 64 bytes. |
| 61 | * playback hw constraints require period_size = n * 64 bytes. |
