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.
Karsten Wiese4f550df2005-10-18 14:31:07 +020044 *
45 * Sep. 26, 2005 Karsten Wiese <annabellesgarden@yahoo.de>
46 * - Optimize position calculation for the 823x chips.
