I am a newbie...I just installed redhat9.0. I have the cm8738 sound card. the system see's the sound card but doesn't play sound. PLease HELP!!!!!!!!!!!!
I hope you're not trying to play any mp3s without the mp3 patch for RedHat... . Anyway, I have an CMI8738, and you should have the module loaded into the kernel. lsmod tells you what modules are running. Check wether you have Alsa installed. If you do try alsaconf and see if the program detects your card correctly. If everything went ok with alsaconf, execute alsamixer and see if you can set volumes. If you can, listen to the output on the earphones/speakers. The statics should give you a hint wether it works. If alsamoxers fires up and show you the volume levels, that means, it should be morking OK. try playing some souds. Any sound will do EXCEPT mp3 (unless you have installed the red hat patch). Give some more details (errors - alsaconf/alsamixer & co, lsmod output as LaraDevil94 said.
Absolute newbie here ^^. I got the similar problem. I'm running on Red Hat 8.0 and i have the CMI-8738 onboard.
And from my GNOME menu->System setting->Soundcard detection ,it is recognised as CM8738 and its module is
DISABLED!!! HELP.....Please...
So both of you have RH... RH has a hardware detection tool - kudzu I belive, check it out. I'm a MDK fan, so I don't know exactly what config tools RH has in there for you. Kudzu I know 4 sure. Try it. Next, make sure you have ALSA installed. It's done its job, detecting even ISA SoundBlaster AWE64 cards. So... Install alsa&co, making sure you have alsaconf installed. Run it... It should be an ncurse app, so run it as root in a console. (su to root or login on a terminal - CTRL+ALT+Fx as root). It should dispay some warnings in case alsa is running, skip over it, and let it search the cards database.
If it finds your CMedia CMI-8738 PCI card, you should be about done... alsa should take care of installing the modules for you. After it's done, check the sound. DON'T PLAY MP3s, as they will fail unelss you have the patch for RH. Sndconfig might proove useful. Dunno if it will work OK on RH9, but if alsaconf fails, give it a try and post the errors U get (in case you'll get errors )
I have MDK 9.2 and the consensus of all the posts I've read is that I need to recompile the kernel-source. Now I've been working on getting the kernel -source but there aren't any instructions anywhere. I'ver read that 9.2 doesn't come with kernel-source and I've read that I can boot the install disk and choose "upgrade" to install the source - Not True. Some simple and true instructions on how to get an Aureal soundcard on a Vortex2 chipset to work with MDK9.2 would be nice.
Hi ! I have a problem.... I have a built-in soundcard C-Media 8738. With the precompiled 2.4.22-1.2129.nptl kernel (on RH, Fedora Core) it works good. But if I compile 2.6.7, 2.6.8.1 kernels and restart KDE, it says, it couldn't open device /dev/dsp . But if I do " modprobe cmpci ", OSS begin to work, although aRTs doesn't work... Redhat soundconfiguring says, my soundcard isn't compatable. Say me please, how I must configure my 2.6.8.1 kernel for working aRTs and OSS ?
