Setup Issue - NeoMagic NM256 on HP Omnibook 900 F1712WT with Debian 4.0


Status: Partially Resolved

Well, after four months my issue is partially resolved. After having installed Debian 4.0, and having looked practically all over the Net yet again, I came across something in the Ubuntu forums about an alsa configuration on Ubuntu that worked for the same model laptop as I. So I figured I'd run alsaconf with the aggressive IRQ/DMA search.

It came up with module 'snd-sb8', using io=0x220, irq=5, and dma=3. Upon running alsamixer, I am able to set volumes, and unmute outputs, and in KDE control center, I am able to start KDE's alsa support without getting the 'no such device' message.

But I still get no sound.
New information is being posted.

Original message follows -- Anything no longer valid has been diked out.

I'm having troubles getting sound to work in the setup mentioned in the title. Google has been no help to me, I keep on getting solutions that when attempted don't yield anything -- even the ones that should work like running 'alsaconf', using other drivers, etc.

What can I do to get sound working, considering everything I've already tried? I'm generally adept in computers, but not a Linux guru yet, but haven't discounted the fact that my google-fu isn't as strong as I'd like it to be either.

from what you posted, it should work. You've probably done this, but, did you run alsamixer to turn of the volume, then alsactl store?

as root type "cat /dev/urandom > /dev/dsp"
if ur sound works you'll know it =P
ctrl c to kill it

if you still have problems get a newer kernel

Chris, I've tried 'cat /dev/urandom > /dev/dsp' as root, and I get an error saying No Such Device.
I'm not at my laptop now, but when I get back to my laptop I'll tell you exactly what the error message is.

i would definately update your kernel if your not getting /dev/dsp. I bet alsa is compiled seperately in your current kernel. If your new to compiling kernels i would suggest using the .config from your 2.6.8 and double check that alsa is enabled.

I installed the kernel 2.6.18-3-686, and I'm still having problems.

Whenever I run alsaconf, I get this error, and it interferes with all terminal operations. It repeats until I reboot the computer.

specify port
snd_cs4231: probe of snd_cs4231.0 failed with error -22
CS4231 soundcard not found or device busy

I have a dell laptop with the same soundchip - it took me ages to get it working.

Your OS is probing for CS4231, but you already have nm256 loaded, I guess you have a conflict there. Some people have had success using the cs42* drivers for neomagic chipsets, but I have had more joy with nm256 (and I have the same lspci listing as you even down to the rev 20)
Maybe you could blacklist cs4231 in your system, and see what happens. how to do that depends on whether you use hotpug or udev, sorry I'm not a debian user.



what I did:
download Alsa from http://www.alsa-project.org/
and follow the info here:
