The sound card is an on board one.
class: AUDIO bus: PCI detached: 0 desc: "nVidia Corporation MCP61 High Definition Audio" vendorId: 10de deviceId: 03f0 subVendorId: 1849 subDeviceId: 0862 pciType: 1 pcidom: ? ?0 pcibus: ?0 pcidev: ?5 pcifn: ?0

The sound card detection program does see it but no sound come out when I test it. I'm not sure but I think that the nvidia chip set may be quite a new one and I'm beginning to think it might not be supported yet in Linux.
The listing for a driver implies that it is supported. This might be a dumb question, but did you check the volume settings in the mixer app?
Not such a dumb question, I had tried running the alsamixer command when I had F7 installed but not after getting rid of F7 and installing CentOS. I have just tried the command from the cli and here is what I got.
[john@localhost ~]$ alsamixer
alsamixer: function snd_ctl_open failed for default: No such device [john@localhost ~]$
When KDE starts up it gives me a error message about the sound problem. Next time I reboot I will make a note of what it is. I know that the speakers are plugged into the correct socket as this machine is one of two that dual boots windozs and I get sound when I run windoz to play games. I'm off to bed now as its just past 5am so will shut down this box and have another try later on today. Thanks for the help so far though.
That means the driver isn't loaded. 'modprobe snd-mpu401' as root and try again.
