I backported some sound file code from the 2.4.22 kernel (patch bk29) into the redhat9 kernel and was able to get sound to work on the dell 4600. The 4600's I have use the ich5/ads112 integrated sound. rh9 doesn't recognize this device. The important files to backport are: include/linux/ac97_codec.h include/linux/interrupt.h drivers/sound/Makefile drivers/sound/ac97_codec.c drivers/sound/ac97_plugin_ad1980.c drivers/sound/ac97_plugin_wm97xx.c drivers/sound/i810_audio.c The i810_audio.c file needed some slight tweaks to use the older calls for mem_map_reserve(), mem_map_unreserve(), and remap_page_range(). After building/booting the kernel the sound is available from the black "surround" jack but not the green line-out jack or the headphone jack. I'm sure getting sound out of the line-out and headphone jack will just involve some slight hacking of the driver by those who know more about this sound chip's registers and bits. In the meantime I have sound under rh9 without running the newer kernel.
