These comments should be only one comment. See also the recent commit
c3a832a7fb26fed8fd7834e96f09e3565b637f69, which updated the manual to
explain how such comments should be written.

These empty new lines are not needed.

You have selected BR2_PACKAGE_ALSA_LIB above, but you don't depend on
them. Unless alsa-lib is a runtime-only dependency, and not a
build-dependency, this is wrong.

Also, I believe that since the dependency list is not too long, putting
it on one line is ok:

JACK2_DEPENDENCIES = libsamplerate libsndfile alsa-lib

Thanks!

Thomas
