Sorry, but latest CVS does not work. Sound is still very distorted. CVS from 2002-12-09 12:00 works well though, which is what I'm using now :) It is using version 1.37 alsa-kernel/pci/cs46xx/cs46xx_lib.cc.
Current CVS still seems to be broken. The hercules_init(...) function will reset the EGPIO's to default state turning of the amplifier. This patch changes the initialization order calling amplifier_ctrl(...) after mixer_init.
