 I assume you wrote "/dev/cd0" instead of "dev/cd0" and that a cd is indeed
inserted.
Are you trying to listen to it from speakers of from headphones? Many times,
headphones are badly configured by default and need a little work from users.
Do you hear sound with headphones detached?

Output of "mixer" command could help.
