In my opinion, this is the cleanest way to do it:

- First add your account to the 'audio' group:

edit /etc/group and find the line that starts with 'audio'. Add your 
account after the colons. For instance In my '/etc/group' have:

audio::17:cesarem

The group number could be different.

- Then edit /etc/udev/rules.d/udev.rules:

Find the line that starts with ' "KERNEL="event*", '. Change the 
permissions as "0660" and add the 'audio' group.

Here I have:

KERNEL="event*",        NAME="input/%k", MODE="0660", GROUP="audio"
