Unhappy AC97 and i810 problems.. plzzzzzzzzzzzz help


Hi guys,
I am using RH 8 and have onboard audio. The chip is intel 845 GL. and i am not getting any sound. When i login to the system it says, failed to initialize device no such device as /dev/dsp0....
Then i tried sound card detection, it gives me the following
Vendor: intel corp
model: 82801DB AC
module: i810_audio

if i click on play test sound i dont hear any thing. i keep my speakers in full volume... and there is no volume control button...

then i read some of the posts here, so i downloaded ALSA drivers alsa-driver-0.9.2 from the alsa-org website. and installed those drivers. IT took a looong time to install. and finally it finished an i thought i would be able to listen to some music but again in vain

Then i logged in as root and tried lspci and i got this
[root@localhost root]# lspci
00:00.0 Host bridge: Intel Corp. 82845G/GL [Brookdale-G] Chipset Host Bridge (rev 01)
00:02.0 VGA compatible controller: Intel Corp. 82845G/GL [Brookdale-G] Chipset Integrated Graphics Device (rev 01)

00:1f.0 ISA bridge: Intel Corp. 82801DB ISA Bridge (LPC) (rev 01)
00:1f.1 IDE interface: Intel Corp. 82801DB ICH4 IDE (rev 01)
00:1f.3 SMBus: Intel Corp. 82801DB SMBus (rev 01)

02:09.0 Communication controller: Conexant HSF 56k HSFi Modem (rev 01)


then i did modprobe i810* and i got this

[root@localhost root]# modprobe i810*
/lib/modules/2.4.18-14/kernel/drivers/char/i810_rng.o: init_module: No such device

then i also tried chmod 666 dsp*

But all efforts in vain...

Did i miss anything important here??? Please let me know guys, cause i am a newbie in linux and have no idea... I totally depend on ur advices...

Thanks,
Vijay Venkatesh

No, it doesn't :)

Have a good read on The Linux Documentation Project.

That just means that the modules that are installed
are mismatched. What you'll have to do is
described in the Howto from the link above.

Good luck, if something is unclear in the
Howto just call back in :)

Cheers,
Tink
