From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050323 Firefox/1.0.2 Fedora/1.0.2-1.3.1
Description of problem:
New HP m7060n Media Center PC. (Private ASUS motherboard with integrated sound.)
Install FC3 core (workstation config) from scratch.
Sound chip is not detected.
Core is "up2date"
From Specs sheet:
Integrated Intel High Definition (TM) audio (Azalia)
o Realtek ALC 880 chipset
o THX certification support
o 8-channels for Full Dolby 5.1/6.1/7.1 surround sound support with Dolby Pro Logic IIx
o Dolby 5.1
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Blow away Fedora Install
2. Install from FC3 DVD
3. Follow all prompts.
4. Kudzu detects 8802 chip on first boot, click "configure", Kudzu disappears.
5. /usr/bin/system-config-soundcard => "No Soundcards were detected."
Actual Results: Anaconda does not prompt for any sound card information during install.
Kudzu detects "new hardware" but "configure" just makes it go away.
Expected Results: Ideally, sound system would be detected and configured and I could continue to be an ignorant newbie and just enjoy using Fedora instead of "the other OS" which works fine with the hardware.
I could not find anything similar enough using search facilities, this seems to be the stuff that experts ask for:

Current sound drivers in Linux don't support this hardware for sound
output. You can send your request directly to ALSA project,
www.alsa-project.org and people here can make driver for your sound card.
For future readers:
This board is supported in ALSA 1.0.9rc2.
My sound system is now functional.
Thanks for your assistance.
