Thanks for the suggestion regarding the centre, I fooled around with this and did get a "beep" heard through the headphones.

I'm sorry to have another dumb beginner question--when I place an audio cd into the cdrom nothing happens. When I try as su

mount cdaudio , mount cdrom , mount etc., I get an error that in /etc/mtab or /etc/fstab there is not a proper entry. Looking at /etc/fstab

# /etc/fstab: filesystem table.
#
# filesystem mountpoint type options dump pass
/dev/hda2 / ext3 defaults,errors=remount-ro 0 1

proc /proc proc defaults 0 0
/dev/fd0 /floppy vfat defaults,user,noauto,showexec,umask=022 0 0
usbdevfs /proc/bus/usb usbdevfs defaults 0 0
sysfs /sys sysfs defaults 0 0

/dev/cdaudio /cdaudio iso9660 defaults,ro,user,noexec,noauto 0 0
# Added by KNOPPIX
/dev/hda1 none swap defaults 0 0


for /etc/mtab there does not seem to be such an entry,

/dev/hda2 / ext3 rw,errors=remount-ro 0 0
proc /proc proc rw 0 0
/dev/pts /dev/pts devpts rw 0 0
usbdevfs /proc/bus/usb usbdevfs rw 0 0
capifs /dev/capi capifs rw,mode=0666 0 0

I'll check the user forum about this issue, but just report the observation.

Thanks again for the centre suggestion, I had no idea about this resource,
cheers,
