Hi,I installed DSL 4.0 RC5 on a Compaq Presario 1207
(32Mb RAM, 1,7Gb HDD, CDROM, Floppy, fb800x600)
and the installation work out easy and swift.
The only thing to have a music playing typewriter is the DSL-package of abiwork and some ogg music files. So I burned the files on a CD and verfied it.
The problem is that I can't mount the CD nor can I play a music CD via xmms (digital track reading is nessesary).
Playing the music tracks via xmms (anaolg) works, but since there is no cable connection to the soundcard I won't hear a tone.
What might be the problem or is there a workaround ?
Regards,
Marcus

Hi mikshaw,you are right
the missing cable will prevent hearing music while playing xmms in analog mode.
The more importend problem is that xmms can't use the digital mode to access the tracks.
The thing is that mount can't access the CDROM neighter can XMMS.

So the mount command actually fails? This should have nothing to do with an audio cable, but more likely an issue with your drive. You're sure this is an ogg CD you're trying to mount, and not an audio CD? Some burning software might automatically convert the ogg files to CD tracks.

this is a normal data-CD - I verified it with another Linux system.That should not be the problem.

I found the problem 
the DMA support was activated for both IDE drives the HDD (it's ok) and for /dev/hdc (it's not ok).

| Code Sample |
| hdparm -d0 /dev/hdc |
But how do I change it in a config file ??Regards,

Well, congrats on finding the answer. I wouldn't have suspected dma.You apparently have "dma" in your boot options. I'd remove that and add device-specific command to /opt/bootlocal.sh (and make sure that file is backed up and restored).
Something like this should work:
| Code Sample |
| for DEVICE in hda1 hda2 hdd; do hdparm -d1 /dev/${DEVICE} done |
Replace the device names in the first line with your own
