In my experience, "decent" is overoptimistic. Sound _output_ tends to
be quite ok for a number of purposes, sound input is where you are
usually a lot better off using an external soundcard unless you are
talking about voicecall-compatible quality (and many laptops indeed have
combined microphone/headphone sockets for headsets). Of course, the
kind of soundcard for $20 when new does not offer better quality either
but might have different input/output/level/mixer options ("surround
sound" and its ilk, for example).
What I sometimes find annoying is that laptop built-in devices tend to
have more comprehensive ALSA support particularly regarding the mixer
than external soundcards but it's probably due to more people being in
possession of them.
