I would first the obvious: your laptop might not have an audio cable |
| 13 |
attached to the audio output of your drive, or the drive might not have |
| 14 |
such output at all, or maybe your mother board has not an audiocd/aux |
| 15 |
audio input port. Try any audio program that can do digital audio |
| 16 |
extraction. Xmms can do that, I can't think of any other, maybe kscd |
| 17 |
has it, but you might need to enable it manually on its config. I don't |
| 18 |
really know. |

If that works, we found the problem. |

DMA problems are usually related to the performance of the drive, and the |
| 23 |
amount of cpu cycles the bus sucks to do any job (with DMA mastering the bus |
| 24 |
can work unattended, making your cpu happy and your battery even happier), |
| 25 |
but, unless the performance is so so so bad, this is not usually a problem |
| 26 |
to play an audiocd (they can be player in 1x drives, I swear cause I had one |
| 27 |
years ago, and there were no UDMA by that time). |
