/*
|
|
* Changes:
|
|
*
|
|
* Dec. 19, 2002 Takashi Iwai <tiwai@suse.de>
|
|
* - 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 <annabellesgarden@yahoo.de>
|
|
* - Optimize position calculation for the 823x chips.
