It, sure, is no top of the line equipment and as I mostly listen to CDs, I barely use built-in sound for anything other than movies — in which case quality isn't the cornerstone, but I can't say that it's noisy in either of my laptops, including very old (ancient? medieval?😅) ThinkPads — of course you have to explicitly mute all the inputs: CD, mic, line in — and at times even more obscure shit that codec might support, but is rarely even wired to anything — this shit is usually what picks up the noise. I dunno, maybe some soundcards' kernel modules dont export these and they aren't available in mixer software, getting rid of noise in this case might indeed be problematic 🤔
