Testing a patch is quite easy.

If you are an Ubuntu user, you can try the instructions at
https://help.ubuntu.com/community/HdaIntelSoundHowto
and specifically the script mentioned in the section “Update to the
Latest Version of ALSA”.

With this script and the instructions from the wiki page,
1. you can install all required packages that are needed to compile
the latest Alsa
2. you can apply a new patch (you do this manually), recompile and
test without having to reboot.
3. you can revert to the previous state

The script downloads by default the following
ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz
I suppose this is the one you need with the latest version.

Good luck,
Simos
