From 27fe864ec9e61041fc0b6f680207ae84f359b502 Mon Sep 17 00:00:00 2001 From: James Courtier-Dutton Date: Wed, 21 Dec 2005 15:06:08 +0100 Subject: [ALSA] snd-emu10k1: Removes some distortion from Audigy 2 ZS Notebook. Modules: EMU10K1/EMU10K2 driver Description: Part way to fix ALSA bug#927 Add support for the SPI interface on the CA0108 chip. This is used to control the registers on the DAC. Headphone output tested. Other outputs and Capture not tested yet. Note: The red LED does not come on, but sound is still OK.
