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 at localhost ~]$ alsamixer alsamixer: function snd_ctl_open failed for default: No such device [john at 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. -- Guy Fawkes, the only man to enter the house's of Parliament with honest intentions, (he was going to blow them up!) Registered Linux user number 414240
