Making sound work on a laptop
 
Hi,

Here is an open question for everybody from those hundreds like me who face problems in making their sound card work.

Can somebody explain the step by step procedure of how to do this(if u r kind enough)
If you are generic enough the answer will suit anybody

Here are some assumptions:

1) I cannot find the chipset of the soundcard(it is enclosed, i don't want to rip the laptop)

2) I know for sure the card is working very well under Windows XP(And I know the driver XP uses)

3) I am using a 2.6.x kernel and comfortable with compiling it if required

Yes you can, from the virtual console (the command prompt) or xterm session type:

/sbin/lspci -v

With this information you can then visit the alsa-project site and find information about the sound configuration; http://bugtrack.alsa-project.org/mai...hp/Matrix:Main

You can also search around here; http://www.linux-laptop.net/

And this sound interface driver is ?????

In most cases this is not needed.

linux driver coming with kernel?
 
Thanks.

linux(FC6 stock kernel) seems to have found the correct device and a driver for it.
sound works but very poor in my case.
as i remember(since my laptop is at home and i'm online from my office i can't lspci) it says about a Intel device and the module is snd-hda-intel and in gnome-sound-detection it shows a device name like xxx from Intel Coporation.

But in windows the driver says its a Conexant High Definition Audio driver.
So i just wonder linux has not identified it correctly(but i realy do think linux very smart :-))

and the alsa package had version 1.0.12 as opposed to 1.0.14 which is the current release. somewhere i read that i have to have the latest alsa package... and somewhere else it was said that with the 2.6.20 kernel it works ...
i'm a bit confused...

Well the name used by Windows may say one thing and the driver is really something else.

Yes the latest is alsa does work well with the 2.6.20 kernel or newer. Both can be applied to FC5 by various means. Personally I prefer building my own kernels, but FC5 does have a 2.6.20 series built kernel available;

Maybe you need to do something like: yum update

The Fedora Core Development alsa rpm packages may work with Fedora Core 5 but I cannot say for sure. Get the list of the current alsa rpm packages by typing something like;

/bin/rpm -qa 'alsa*'

Down the newer development rpm versions and test install; /bin/rpm -uvh alsa*.rpm --test
if you get no errors then remove the --test switch and really install.

Great it worked !! hugs to alsa

Here is what i did,
1) found audio device by lspci -v
2) go to alsa sound device matrix found which driver suits it
3) followed the procedure in it
4) PLAY !!
simple as that
