(gentoo) onboard intel 82801G audio

RESOLVED! (see second post for guide)

I've been having fun the last few days bringing up a gentoo system that crashed midway through installation. So far all's been going pretty well, and I've just got KDE running. Naturally, the first thing I was greeted with was an error message: aRts will output sound to null because /dev/dsp does not exist. A quick "ls -R /dev/ | grep dsp" confirms this.

I hadn't been trying to listen to music through the console, but went back, and, sure enough, no sound there either. Also, no sound as root, so it's not a permissions problem.

lsmod returns only ndiswrapper's information (yes, that's the only module loaded), and the relevant section of lspci -v is as follows:

Code:

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
        Subsystem: Intel Corporation Unknown device 0014
        Flags: bus master, fast devsel, latency 0, IRQ 9
        Memory at 90300000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: [50] Power Management version 2
        Capabilities: [60] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable-
        Capabilities: [70] Express Unknown type IRQ 0

.

I've tried switching around the drivers between oss and alsa, but to no avail. Also, there's no sound in the the gentoo Live CD, but there is in an old Ubuntu (6.10) that I had laying around.

I have emerged alsa, alsa-tools, and alsa-utils, since none of these were around at first.

I should note that I have been missing many important packages from the get-go; I even had to grab sudo and dhclient with windows to get online. Also, my kernel is a custom 2.6.21.1 . Sound does not, however, work with the stock kernel (2.6.17.13), which I have kept around. But then, it didn't on the liveCD either. (same problem)

That's actually what I'm following right now. I'm doing a world emerge, though (261 of 265! woohoo!), so it'll be a while before I can reboot (had to recompile the kernel). I didn't see it before I made the post. I'm going the kernel modules route, first at least.

Also, had to unmerge alsa-drivers, which I had installed before I knew it would conflict with the kernel support.

Make sure to run revdep-rebuild

rebooted, and did a crapload of insmods and modprobes. lsmod now returns

Code:

snd_pcm_oss            26400  1
snd_mixer_oss          16896  1 snd_pcm_oss
snd_seq                44080  0
snd_seq_device          9352  0
snd_hda_intel          19224  1
snd_hda_codec         198528  1 snd_hda_intel
snd_pcm                64516  3 snd_pcm_oss,snd_hda_intel,snd_hda_codec
snd_timer              20100  2 snd_seq,snd_pcm
snd                    42340  8 snd_pcm_oss,snd_mixer_oss,snd_seq,snd_seq_device,snd_hda_intel,snd_hda_codec,snd_pcm,snd_timer
soundcore               9568  2 snd
ndiswrapper           166100  0
snd_page_alloc         11144  2 snd_hda_intel,snd_pcm

arts still crashed when I started kde, but that's because I hadn't loaded snd-pcm-oss and snd-mixer-oss. Amarok and MPlayer output works fine through aRts. I couldn't be happier.

Now all I have to do is add all that stuff to my boot scripts, which I know I can do. Thanks for the help!
