Just means alsa doesn't know about your sound card, assuming you have one installed. Installing the latest version of alsa might help. Googling for "linux alsa config" will give you quite a bit of advice. Also, knowing what distro and version you are using will help people here help you. You should include that info with every question, whether you think it'll matter or not. You'll have a much better chance of people taking the time to help you.

Good luck....

thank u for ur reply
iam using fedora2
how can i know whether soundcard is present or not in my system without having the drivers.
otherwise how can i know my hardware components from command prompt
thank u very much

Fedora 2 is damn old. There is a very good chance it'll just work with the latest version of Fedora. You can get the drivers very easily, if you don't want to upgrade. Fedora 2 though, you shouldn't really be using something that old, Fedora 8 is out already, and something as old as Fedora 2 probably isn't secure anymore anyway, not to mention newer versions of applications, and bug fixes.

Good luck...

you may not have an alsa sound card, have you tried oss instead?

thank u ,
actually iam connected to set top box in that we have only fedora2 .
so intially how i know whether sound card present in system or not
is there any command.
and how can i try "oss".
thank u
sree

I'm sorry, I don't know of any linux command offhand that would identify your sound card. I think the best way to solve this problem would be to install the latest alsa drivers and then let alsa tell you. Here are the alsa downloads you need. You need 3 of them. Alsa-drivers Alsa-lib and Alsa-util. Get them from here...

Here are some instructions on how to install the drivers.

http://tldp.org/HOWTO/Alsa-sound-4.html

It looks like an old howto, but I think it's still accurate. Once alsa is installed, you can use "aplay -l" to list all your audio devices. The "dmesg" command may help, it will give off quit a bit of info, but if you dig through it you might see your sound card listed, but maybe not too. Your best bet is to install the latest alsa drivers, but if you can't do that, then dmesg is your next best bet. I wouldn't hope for much there though....another thing you could do would be to use a live cd like puppylinux or knoppix. They'd both detect your hardware and you could just look it up with the "aplay -l" command.

Good luck...

Let us know how it goes....
