Hardware : Intel atom (COM)
Audio - ALC 888

OS : Ubuntu 9.04

Observation : Sound Card not getting detected.


-> I downloaded High Def. Audio Codec drivers as " LinuxPkg_5.13rc9.tar.bz2" from RealTek site, compiled and installed the drivers.
-> But while installation I got a GUI saying "No PnP or PCI audio card detected".
-> lspci command shows all other pci connected devices except sound card(ALC888).
->I tried recompilation of Linux kernel to make HDA Codec as a Built-in modules (built-in ALSA driver support) ,but still there was no change in behaviour.

Pls share your valuable ideas...

try 'sudo lspci -v |less' in a terminal without the quotes. Can you find your soundcard?
If not, check seating etc with the box unplugged.

I had done that...That was the point 3 reproduced below..

-> lspci command shows all other pci connected devices except sound card(ALC888)

Its not shown there in lspci...I dont think it is a seating problem,since I had tried it and further it is a COM module...

Ok, are you sitting down?
There's a _lot_ ot ways things can go wrong, not least faulty hardware on a soundcard. If you can't get lspci to read the basics of it's existence, the glaringly obvious possibility is that it doesn't exist - it's blown somehow. Try another pci slot, then try another card in there. Any type of card - check that it's not a m/b issue.

its was a seating problem..got solved when I pushed it with rage..

I think we've all been caught by that sometime. Glad you found it.
