Update, with sounds now working.
To set the scene, I installed F8 on this new machine that I'd built, and it
installed ok (caveat: I had to disable ACPI in the BIOS, otherwise I couldn't
boot any install disc, or live CD). The kernel that was installed is
18.104.22.168-42.fc8, using Alsa driver 1.0.15 IIRC. Neither the soundcard, or the
onboard Ethernet card were detected. As I wanted to do the updates for F8, I
went into the BIOS, and disabled the onboard NIC, and as it turns out, also
disabled the Azalia audio. Installed the Realtek 8139 PCI NIC, and the
network is now working.
I now took the machine upstairs, so as to be able to plug it into my Ethernet
switch, booted up, and logged into Gnome. I don't use Gnome, but logging into
KDE resulted in a dead mouse, and keyboard, and needed a hard reset to exit
KDE, and then reboot. I think there was a problem, either with just the
2.6.23 kernel, or perhaps also with other needed updates, which caused F8
post install to not play well with this Asus M2N-X Plus mobo.
Ok this is as far as I got with my last reply, as I was downloading the
updates. Updates now installed, and now have kernel 22.214.171.124-10.fc8, and Alsa
Reboot with the new kernel, login to KDE which now is ok, but still no sound,
and nothing in /proc/asound/cards. Reboot, and check the Azalia setting in
the BIOS, and yes, I'd forgotten that I'd disabled it. Set it to auto, then
boot up. Miracle of miracles, the sound now works.
I must admit, that having tried to help out on various lists with hda intel
problems, I was probably a bit paranoid, and didn't seriously expect the hda
intel card to work on this machine. Speaker-test only outputs on left front.
KDE's sound test plays ok. An audio CD wouldn't output any sound, until I
realised that I hadn't been able to find an analogue audio cable for the
optical drive. Changing a setting to direct digital output fixed that
I'd already removed the alsa-plugins-pulseaudio package, as I had problems
with pulseaudio on my other F8 install. Alsamixer doesn't show many sliders,
but I think that is normal with hda intel cards, compared to my Audigy2
soundblaster one, which has sliders for everything under the sun.
I may try some of the model options for the hda intel card, but it seems to be
producing sounds ok with the default. Speaker-test just trying left front is
Anyway sounds work, and I rebooted, entered the BIOS, and re-enabled the
onboard NIC, which is now detected ok. I think that the later 2.6.25 kernel,
along with all the other updates were needed to get F8 to work well with this
I havn't updated the alsa driver to the latest, as the sounds appear to be
working ok, but as there is a whole bunch of freespace on this harddrive, I
may install another instance of F8, and update the alsa driver to see if
there are any differences. I've re-run the alsa-info.sh script with sounds
now working, and the link is below.
Thanks Stan, and all you other folks at Alsa-devel who are working on
resolving Alsa driver problems.
