The most likely case is that your system does not support direct audio from the CD drive and that you need to play your CDs with a different application (instead of just a hardware command). It used to be common for an audio signal cable to be connected directly from the CD drive to a specific CD input on the audio mixer. The 'cdcontrol play' command directs the CD drive to start playing audio. After that everything was done in hardware/firmware with no further OS or application interaction needed. Many current system don't provide this direct audio connection anymore. The audio mixers don't all have input connectors and I don't know if the audio output is even on current DVD drives. I haven't paid attention on recent system hardware assemblies since I don't worry about this anymore. Things to try: We need to see the output of the 'mixer' command. It is possible that the volume control for the CD input is set to 0. My guess is that you don't even have a CD volume control. Look at the output from 'cdcontrol volume'. My system shows 255 for the left and right channels. It is possible that these are 0 on your system thus muting output. Try other audio player applications. Some of them should support playing CDs directly. These application will read the data from the drive and then send it to the system audio. I don't use any of these anymore, I rip everything to mp3 files. Stuart -- I've never been lost; I was once bewildered for three days, but never lost! -- Daniel Boone
