>Description:
VLC cannot play audio CDs when using /dev/cdN on a kernel built with atapicam or with ATA_CAM. One must use /dev/acdN and the "traditionnal" ata interface.

This may become a serious problem for 9.X where ATA_CAM is now the default.

Note that the problem is within VLC, as audio/cdparanoia is perfectly able to extract the cdda content (tested on 8.2 STABLE and 9.0 BETA3).
>How-To-Repeat:

>Fix:
As a workaround, use only kernels built without ATA_CAM.

My limited skills do not permit me to create a patch within a foreseeable future.
