Audio no go on HP dc7900 running FC9

[Richard Vaughn]

Just installed FC9 (w/ updates) on a new HP dc7900 PC.
Cannot get audio of any kind to work.
No sound from internet audio, from music CD's, from sounds on Audio
Prefs;
not to speakers or to USB headphones.

HP support pointed me to Realtek, who they told me was the
manufacturer
of the onboard audio device ("Integrated HD Audio w/ AD1884A codec").

Per HP I downloaded and installed LinuxPkg_5.13.tar.

When I run alsamixer and select F6 (select sound card),
it appears to tell me the card is 'HDA Intel' and the chip
is 'Analog Devices AD1884A'.

Not sure where to go from here. Suggestions?

Thanks,
-Richard Vaughn

I am amazed you even got FC9 to run on that system.
It is using the new Intel ICH10 chipset on the motherboard,
which problaby needs a newer kernel and alsa driver set then
the one in FC9.
You could try disabling the sound handling in the kernel itself
and install the newest alsa driver set (compile it by hand!)
from www.alsa-project.org, they give alsa-driver-1.0.21 as their
current version.
Or otherwise update to Fedora 11, it should work with this
hardware.

It IS a RealTek chipset, but controlled through the ICH10 chipset,
so it _looks_ like an Intel HDA sound adapter.
