I would first the obvious: your laptop might not have an audio cable attached to the audio output of your drive, or the drive might not have such output at all, or maybe your mother board has not an audiocd/aux audio input port. Try any audio program that can do digital audio extraction. Xmms can do that, I can't think of any other, maybe kscd has it, but you might need to enable it manually on its config. I don't really know. If that works, we found the problem. DMA problems are usually related to the performance of the drive, and the amount of cpu cycles the bus sucks to do any job (with DMA mastering the bus can work unattended, making your cpu happy and your battery even happier), but, unless the performance is so so so bad, this is not usually a problem to play an audiocd (they can be player in 1x drives, I swear cause I had one years ago, and there were no UDMA by that time). -- Jesús Guerrero <[EMAIL PROTECTED]> -- [EMAIL PROTECTED] mailing list
