I second this and think that the DMA is a red herring. So first things first: 
run alsamixer in a terminal as a plain user and make sure CD is not 
showing "MM" and is set at a high enough setting.

Then to see what's up with dma:  look at lshw to find its "logical name:".  
Then use the logical name to run:

# hdparm -I /dev/hdc

# hdparm /dev/hdc

(on my machine /dev/hdc is my DVD drive's logical name)

HTH.
