I Can't get any sound to come out of my laptop.

It's a HP Omnibook 4150.
I'm running Gentoo 2.6.12

No supported PnP or PCI card found.

No legacy drivers available

if I type in /etc/init.d/alsasound start I get

Loading Alsa modules...
Could not detect custom Alsa settings. Loading all detected alsa drivers
Unable to find any alsa drivers. Have you compiled alsa-drivers correctly?
ERROR: failed to load necessary drivers
Restoring mixer levels .. .
No mixer config in /etc/asound.state, you have to unmut your card!

when I emerge alsa-driver it says

ALSA is already compiled into the kernel
Please check to make sure these options are set correctly
once you have satisfied these options please try mergin this package again

I've trawled through loads of posts to find an answer. So now I ask for help

thank you

You're most likely going to have to tell the alsa modules some parameters to use; mainly the irq, io, and dma settings. There's a page here that shows those settings being set using the OSS modules, it might give you a direction to go in.

Also, beware of some of those settings conflicting with the pcmcia system on the machine - you may need to tell the pcmica configs to use some alternate port settings in the pcmcia config.opts files - at least that was my case when I have an Omnibook 4100.

Good luck!

Ok, just want to know if anything came of this, I have the Omnibook 4100 and I can't get sound working at all. You said you had to mess with the IRQ's? chipThis website tells me to expect a Crystal CS4237B rev E audio chip, however lspci tells me its a Multimedia audio controller: Neomagic Corporation NM2200 [MagicMedia 256AV audio] (rev12). The drivers aren't working in linux and I'm going to go insane, you said you had it working, could you please explain, in detail, using small words (lol) how you managed it? Thanks man.

This site should be of use to you. it's for an Omnibook 4150, but it's the same neomagic stuffs.
