I'm guessing you're using onboard video. You could safely reduce it to
256MB but 512MB is probably fine unless you really need the extra ram.

Did you install through your packaging manager? Not sure.

'aplay -L' will tell you if you have any devices installed/detected.
Use alsamixer to see if it's been muted which seems to be a common
scenario with certain versions of alsa. If it's still problematic see
if pulseaudio is installed and then troubleshoot that.

Might have a module that the kernel is mistakenly loading or is it be
a multifunction machine scanner/printer? If you can figure out what
scanner module is loading and you're sure you don't want it, blacklist
it (usually /etc/modules or /etc/modules.conf or similar) and try to
configure cups again. I know with my printer I need to install
additional driver packages for it.
