I am a newbie to Fedora and basically to Linux (I do have some limited Solaris experience). I seem to have the same problem as many seem to be having. I have not found a real resolution (at least one that seems to work in my case) for this. I installed Fedora Core 2 on a Dell Optiplec GX1 (this is a test bed system). I did find on a Dell public board that the GX1 seems to have an on board (mother board) Crystal chip set CS4236. Here is what Windows XP shows the sound card as, it is the integrated sound card on the mother board of this system:

Crystal WDM Audio Codec

Device type: Sound, video and game controllers

Manufacturer: Crystal Semiconductor

Location: on Intel 82371AB/EB PCI to ISA bridge (ISA mode)



Crystal WDM Audio Control Registers

Device type: Sound, video and game controllers

Manufacturer: Crystal Semiconductor

Location: on Intel 82371AB/EB PCI to ISA bridge (ISA mode)



Crystal WDM MPU-401 Compatible

Device type: Sound, video and game controllers

Manufacturer: Crystal Semiconductor

Location: on Intel 82371AB/EB PCI to ISA bridge (ISA mode)

Here is what the commands that others have suggested be run to help diagnose the problem give me, And I can still not get the sound to work at ALL! Can anyone help me?

Any help would be greatly appreciated.

the other things that give a good idea are dmesg and lsmod. Try lsmod first - and look for a module for a soundcard that sounds like yours. I suspect you won't find one since lspci didn't either. dmesg will tell you if the soundcard announced itself at boot - if it does, then it would sound like you need to get a module for it. Of course - Fedora may not support the card...

This from fedora-config-list

Soundcard Detection utility is not able to find a sound card.
Hardware Browser has 3 devices under sound. They are CS4236B:Game, CS4236B:MPU, CS4236B:WSS/SB.
Hardware Broser also has 1 device under Unknown Devices. It is CS4236B:Crtl

The PC in question is a Dell Optiplex GX1 with an Intel 440 chipset. The sound device as reported under the WinXP device manager is Crystal WDM Audio Codec.

Only one and no replies yet.
Notice that this guy has the game, MPU, WSS/SB and controller (Crtl) listed happily.
It would appear that there have been no drivers claiming any of these devices.
Which is probably your problem.

Show us lsmod and dmesg outputs - may help.

Try this....take a look through all of the sound programs that came with the OS and make sure that they are all the way up. I had the same problem, it was only a matter of settings.

Hope this helps,
Eric.

I did get the sound to work by issuing the command modprobe snd-cs4236 I then did have to go Open volume control (in the speaker control on the tool bar) and un-mute and turn up all the volumes (if I tried to do this before I issued the modprobe command I would get Sorry, no mixer elements and/or devices found . However this will only stay this way until I reboot the system again, and then I need to redo the commands and settings again. Can anyone tell me what I need to do to get this to stick. I think I need to modify the modprobe.conf file and maybe and rc.x file but not sure just what to set where.

Thanks for any help,

Jim Rausch

I just started playing with the exact same Dell and same error. I am running blag10000 a fedora 2 type linux. I found this command: sndconfig and ran from command line and now my speaker card works sortof. It works for sound but not for microphone (dont know about line in). Hope this helps.
