For me, the main issue with laptops is the audio hardware, not the
distribution. The analogue part of their combined mic/line audio inputs
are optimized for a sound level of 0dB, which correspond to their line
In order to get the best possible sound of it, you must set the input
level at 0dB with alsamixer, run a vu-meter, connect it to the input
and use an external mixer or device to set the recording level on the
vu-meter. That way, you can get a decent sound quality even with the
built-in audio card.
Also, less important but still important if you want to get the best
out of the hardware - you must test the sound card with different
sampling rates. It was discussions here in the past, pointing the fact
that many cheap sound cards A/D converters are always working at a
fixed sampling frequency (at the maximum sampling rate frequency the
card can do), and that the card will make a sampling rate conversion
when the JACK/ALSA sampling rate is lower. Cheap hardware imply cheap
conversion with a lot of aliasing artefacts, and it will be better to
use the highest sampling rate the card can do for recording, and to make
a software sampling rate conversion afterwards.

If you have a problem and you are not doing anything to fix it, you are
at the heart of the problem.
