I quickly learned in my time with Linux that internal sound-cards will only lead to frustration and misery. Support is flakey (as shown in this article), half the features you'd want as an audio enthusiast aren't available on Linux from the manufacturer (Graphic EQ, GUI control panel, etc), and oftentimes you still may even get interference hissing/beeps if the EMF shielding isn't up to snuff since the inside of the case is the worst place for sound hardware to be.
