Preferences -> Plug-ins -> Input -> check the 'in_cdda.dll' entry & that will attempt to live load the CD plug-in.
Out of the box new installs will now disable that plug-in as there is a performance impact from it & with a general shift towards machines not having CD/DVD drives, it made sense to install it but set it to be disabled as it's then simple enough to just enable it if needed.
