| * Cirrus Logic, Inc. |
| * Routines for control of Cirrus Logic CS461x chips |
| * |
| * KNOWN BUGS: |
| * - Sometimes the SPDIF input DSP tasks get's unsynchronized |
| * and the SPDIF get somewhat "distorcionated", or/and left right channel |
| * are swapped. To get around this problem when it happens, mute and unmute |
| * the SPDIF input mixer control. |
| * - On the Hercules Game Theater XP the amplifier are sometimes turned |
| * off on inadecuate moments which causes distorcions on sound. |
| * |
| * TODO: |
| * - Secondary CODEC on some soundcards |
| * - SPDIF input support for other sample rates then 48khz |
| * - Posibility to mix the SPDIF output with analog sources. |
| * - PCM channels for Center and LFE on secondary codec |
| * |
| * NOTE: with CONFIG_SND_CS46XX_NEW_DSP unset uses old DSP image (which |
| * is default configuration), no SPDIF, no secondary codec, no |
| * multi channel PCM. But known to work. |
| * |
| * FINALLY: A credit to the developers Tom and Jordan |
| * at Cirrus for have helping me out with the DSP, however we |
| * still don't have sufficient documentation and technical |
| * references to be able to implement all fancy feutures |
| * supported by the cs46xx DSP's. |
