| 4 | * Cirrus Logic, Inc. |
| 5 | * Routines for control of Cirrus Logic CS461x chips |
| 6 | * |
| 7 | * KNOWN BUGS: |
| 8 | * - Sometimes the SPDIF input DSP tasks get's unsynchronized |
| 9 | * and the SPDIF get somewhat "distorcionated", or/and left right channel |
| 10 | * are swapped. To get around this problem when it happens, mute and unmute |
Joe Perches | 561de31 | 2007-12-18 13:13:47 +0100 | [diff] [blame] | 11 | * the SPDIF input mixer control. |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 12 | * - On the Hercules Game Theater XP the amplifier are sometimes turned |
| 13 | * off on inadecuate moments which causes distorcions on sound. |
| 14 | * |
| 15 | * TODO: |
| 16 | * - Secondary CODEC on some soundcards |
| 17 | * - SPDIF input support for other sample rates then 48khz |
| 18 | * - Posibility to mix the SPDIF output with analog sources. |
| 19 | * - PCM channels for Center and LFE on secondary codec |
| 20 | * |
| 21 | * NOTE: with CONFIG_SND_CS46XX_NEW_DSP unset uses old DSP image (which |
| 22 | * is default configuration), no SPDIF, no secondary codec, no |
| 23 | * multi channel PCM. But known to work. |
| 24 | * |
| 25 | * FINALLY: A credit to the developers Tom and Jordan |
| 26 | * at Cirrus for have helping me out with the DSP, however we |
| 27 | * still don't have sufficient documentation and technical |
| 28 | * references to be able to implement all fancy feutures |
| 29 | * supported by the cs46xx DSP's. |
