It will just side-track you. ..and well.. it can potentially do harm:
you waste time, get angry and hit your [head|wife|...] with the
[keyboard|mouse|..] :-p

more seriously: It will cause problems later when updating.
and more generally: Some software that you install as package might not
be built against this version [of the library] and may not work or
behave strangely (though AFAIK alsa-lib-1.0.24's ABI is backwards
compatible with 1.0.23). And some cutting-edge release might be able to
produce sounds that harm your speakers or ears.. (though you're pretty
save with alsa-lib-1.0.24 there).

In general: Unless you have a _good reason_: don't bother to compile
anything and just use [binary] packages from your distributor.

nope, all of it. Here it creates:
 /tmp/lib64asound2_1.0.24.1-1_i386.deb
 /tmp/lib64asound2-dev_1.0.24.1-1_i386.deb
 /tmp/libasound2_1.0.24.1-1_i386.deb
 /tmp/libasound2-dev_1.0.24.1-1_i386.deb
 /tmp/libasound2-doc_1.0.24.1-1_all.deb

   "Sufficiently new version of libasound not found."

They're not the right version. see /usr/include/alsa/version.h
Apparently the alsa-tools 1.0.24 use some new symbols/functions which
are not present in alsa-lib-1.0.23.

Did you configure specific Input-Devices AND Output-devices in
qjackctl's setup window instead of just setting the interface globally
and leaving those as "default".

does this work?
  /usr/bin/jackd -dalsa -r48000 -p1024 -n2 -D -dhw:1

BTW. IIRC you should not use the -X... options for JACK-midi but rather
use a2j instead. AFAIK there were/are [timing?] issues with the built-in
JACK midi backends. (see Jeremy's workshop slides on how to launch a2j
using qjackctl's "Execute Script" option.)
