I used cdcd from command line. I'll try cdplay... maybe there's more
debugging information.

I doesn't flash. Drive starts spinning when cd is loaded but doesn't
spin when I try to play the disc and returns some error.

Fist thing I double checked when I installed the drive.

That's the second thing I checked. Anyway to be sure I switched the
drive with some old cd burner and everything was ok, so...

No jack or play button in newer drives.

Well... that would be really lame of me :) No, audio stuff is ok.
My main concern is that if the single drive isn't defective and the
problem occurs only in linux (windows has minor issues) I can't return
the unit.
I'll test the drive in some other pc before giving up.
