amixer and alsamixer wont run as regular user

Recently got this problem after upgrading my debian distro. Searched around for a solution and got the help I needed from debian forums.

The problem looks like this:
user@computer:~$ amixer
ALSA lib control_ext.c:664:(snd_ctl_ext_create) ctl_ext: Plugin version mismatch

amixer: Mixer attach default error: No such device or address
user@computer:~$ alsamixer
ALSA lib control_ext.c:664:(snd_ctl_ext_create) ctl_ext: Plugin version mismatch

cannot open mixer: No such device or address
user@computer:~$ 

user@computer:~$ ls -l /dev/snd/

The solution? It was simply deleting the .pulse directory in my home directory.

Thanks goes out to debian forums and the user dmuc for this one.
