Ubuntu 14.04 is one of LTSs, while development for this release already 
finished three years ago. Basically, packages for the release are not 
updated unless some exceptions.

In your case, you can generate alsa-lib related packages with the patch 
by your own. But no one can care of your packages and you need to do 
everything to be required.; e.g. even if you encounter issues from the 
generated packages, no one can help you.

$ sudo apt-get install build-essentials devscripts
$ sudo apt-get build-dep alsa-lib
$ cd /tmp
$ apt-get source alsa-lib
$ cd alsa-lib-*
(apply the patch)
$ dpkg-buildpackage -rfakeroot -uc -b
(packages are generated in higher directory by one level)

Perhaps, the above command lines are not enough. Some packages are still 
missing for packaging.
