Have reviewed a number of threads here regarding no sound and nothing has worked.

I have installed Xandros Pro (trial). I think it is 4.1. This is on a gateway laptop. Hardware detection shows sound card as MCP51 high def audio.

Have run alsaconf a couple of times, no luck. No mixers will run for me (I think kmix is the one that is installed by default and if I run it, it is completely empty - no channels to mute/unmute)

Noticing that after running alsaconf and I try to run alsamixer I get the following:

alsamixer: function snd_ctl_open failed for default: No such device

sellib, I don't think I'm the guy with the solution to your sound problems. But, I think the people most likely to have the answer will want to know more about your sound system. Open a console (click Launch, Applications, System, Console) and enter this command:

Hi
if I get this working for you will you fix my lawnmower.. Laughing

I believe your driver for your on board sound chip is the nVidia MCP51 by your description.
So, this has should be activated by the intel8x0.ko driver which is in
/lib/modules/2.6.18-dcc-smp/kernel/sound/pci

If you do as jimallyn suggests lspci -vv and the beginning of your output is something like
Multimedia audio controller: nVidia Corporation MCP51 AC97 \
Audio Controller (rev a2)
Then ...
Don't know why it was not detected..
Open a console and post this results also..
lsmod
Just mark with mouse Edit/Copy and Paste in post..
..If we don't see we don't see
intel8x0 ...........then we will can insert it below..
If we do then we may have to alter parameters or try the Updated OSS Sound system install which I mention below..

NEXT
as we have a .ko ((Elf binary)) file rather then the .c file ((Text)
I can't have you add to the code like so..
switches something like 0x10de, 0x026b, PCI_ANY_ID, PCI_ANY_ID, 0, 0, DEVICE_NFORCE
but maybe there is a generic already compiled into the elf binary.
..We could do this on the fly with
modprobe and insmod but as OSS/Alsa is already up a reboot may prove necessay anyway.
..I have never worked with this chip but I understand that from Motherboard to Motherboard it can be quirky with LINUX.

If this does not work you may need a Newer OSS update.as this is a newer chip.
http://www.opensound.com/download.cgi
use the LINUX 2.6 (x86)DEB
..But save this until we try the module you have..

So, to start try to add the module into /etc/modules
If it doesn't work we can add switches and/or always remove it.
If it does we can maybe use modules.conf and the update-modules

to try
Launch/Run/ when the box pops up enter
kdesu kate /etc/modules
......Now as the last line enter
intel8x0
do not enter the .ko extention
Next .
File / Save
and then quit and reboot..
I expect you will get some sound but it may not be good as we may have to add parameters after the entry..
Also your SOund is set by default to AutoDetect.. and this may have to be swithed in the Control Center to ALSA although it is not usually necessary.
..Well one step at a time..

Post back.

I found this on their forum ..note the nvidia reference

http://www.4front-tech.com/forum/viewtopic.php?t=2085&highlight=nvidia

THey do state on their page
# OSS v4.0 is here!

* Build 1002 for Linux, Solaris, FreeBSD, SCO OSR6 and UnixWare now available
* Added support for new NVidia MCP61 HDAudio model

So, I would think that the MCP51 is also supported..

Unfortunately this means that Xandros 4 does not have the Dependencies to allow this package to install..

I will look about for another solutions but meanwhile drop an email on TechSupport.
Your card is dectected and it is a possibility to still get it working..
