As far as I know these is not true anymore with newer motherboards.
But since good internal or external soundcards from companies such as
E-mu, M-audio, Tascam, Lexington and many others (just look into the
relevant part of sweetwater.com website) are so cheap, I'd definitely
recommend getting one of these.
The problem with onboard audio cards, even if they improved much in
quality in recent years, is that they may come with various effects,
equalizers, spatializers, TrueBass'es, Wow's and whatever their names
are, which obviousy would interfere with any experiment (and, in my
opnion, music listening as well) unless you explicitly disable them
(and find them in the first place). Semi-pro cards from the companies
like I mentioned above, with their target being recording musicians
not gamers, are much safer in this respect.
For the reasons of flexibility I recommed using a computer and sound
card, not a CD player, unless there are reasons for using a player.
