13 * Changes:
14 *
15 * Dec. 19, 2002 Takashi Iwai <tiwai@suse.de>
16 * - use the DSX channels for the first pcm playback.
17 * (on VIA8233, 8233C and 8235 only)
18 * this will allow you play simultaneously up to 4 streams.
19 * multi-channel playback is assigned to the second device
20 * on these chips.
21 * - support the secondary capture (on VIA8233/C,8235)
22 * - SPDIF support
23 * the DSX3 channel can be used for SPDIF output.
24 * on VIA8233A, this channel is assigned to the second pcm
25 * playback.
26 * the card config of alsa-lib will assign the correct
27 * device for applications.
28 * - clean up the code, separate low-level initialization
29 * routines for each chipset.
30 *
31 * Sep. 26, 2005 Karsten Wiese <annabellesgarden@yahoo.de>
32 * - Optimize position calculation for the 823x chips.
