/* |
|
* Changes: |
|
* |
|
* Dec. 19, 2002 Takashi Iwai <[email protected]> |
|
* - use the DSX channels for the first pcm playback. |
|
* (on VIA8233, 8233C and 8235 only) |
|
* this will allow you play simultaneously up to 4 streams. |
|
* multi-channel playback is assigned to the second device |
|
* on these chips. |
|
* - support the secondary capture (on VIA8233/C,8235) |
|
* - SPDIF support |
|
* the DSX3 channel can be used for SPDIF output. |
|
* on VIA8233A, this channel is assigned to the second pcm |
|
* playback. |
|
* the card config of alsa-lib will assign the correct |
|
* device for applications. |
|
* - clean up the code, separate low-level initialization |
|
* routines for each chipset. |
|
* |
|
* Sep. 26, 2005 Karsten Wiese <[email protected]> |
|
* - Optimize position calculation for the 823x chips. |
