| 27 | * Changes: |
| 28 | * |
| 29 | * Dec. 19, 2002 Takashi Iwai <tiwai@suse.de> |
| 30 | * - use the DSX channels for the first pcm playback. |
| 31 | * (on VIA8233, 8233C and 8235 only) |
| 32 | * this will allow you play simultaneously up to 4 streams. |
| 33 | * multi-channel playback is assigned to the second device |
| 34 | * on these chips. |
| 35 | * - support the secondary capture (on VIA8233/C,8235) |
| 36 | * - SPDIF support |
| 37 | * the DSX3 channel can be used for SPDIF output. |
| 38 | * on VIA8233A, this channel is assigned to the second pcm |
| 39 | * playback. |
| 40 | * the card config of alsa-lib will assign the correct |
| 41 | * device for applications. |
| 42 | * - clean up the code, separate low-level initialization |
| 43 | * routines for each chipset. |
