This is not guaranteed to work, and could lead to all kinds of weird
problems. Alsa-lib is the mechanism by which changes in the kernel side
ALSA are hidden from userspace. They expect to be the same version.
In practice it usually works but there have been some specific incidents
where this caused problems. For example when a major change is made to
a driver the hardware specific parts of alsa-lib will be updated to
reflect the change.
