I have a Cirrus Logic CS 4280 sound controller and from checking my hardware using lspci I get that a Cirrus Logic CS 4614/22/24 controller is installed. I am fairly sure that the drivers are installed correctly (mandrake 9.0) and that the CS 46xx will work for the CS 4280, from reading some previous posts. The problem is I still don't have sound. I have checked both of my volume settings as well as the connections. I have also switched out the speakers, still no sound. Are there some settings in KDE or somewhere else that I'm missing?

If you are using the Mandrake-9 kernel then you probably are using alsa drivers. To see if the drivers are loading do this.

lsmod | grep snd

If they are loaded you can try running alsamixer from a xterm and set the volume levels, particularly Master and PCM. Then <Esc> to exit that.

I tried lsmod | grep and everything seems to be installed correctly. I turned just about everything I could turn up on alsamixer and still no sound. I tried playing a cd, and I can even see the equalizer moving so it looks like I have sound. It seems like a hardware problem but I've tried two different sets of speakers. Still nothing. I turned up the volume on the speakers and the player. I'm sure it is something simple that I'm not seeing. I'm at a loss here. Any help is really appreciated.

Do you hear any systems sounds or just not any audio from an audio CD?

If you are using KDE then go to Configuration -> KDE -> Sound -> Sound System. Click on Sound I/O tab and in Pull down box select Advanced Linux Sound Architecture for the Sound I/O method and click Apply.

I tried setting the Sound I/O method to Advanced Linux Sound Architecture. It didn't work either. I'm tempted to try a pci sound card just to see if it will work. I would have to yank it out of my other computer, but I don't really want to do that. To answer michaelk: I don't have any system sound or any cd audio sound, nothing. Again, thanks for the help.

I found the problem. The volume settings in aumix were set to 0. If anyone else runs into this problem try aumix -q to see what the setting are and aumix man will tell you the commands to control the settings.

I'm having the same exact problem. Except I don't have aumix. All my volume controls are unmuted and up both in gnome and in alsamixer. My audigy sound card is recognized and the drivers are installed and I can see the equalizer jumping, but no sound. Any ideas????
