Bug description:
Can't open "alsamixer". Can't fix my laptop's sound.
My laptop sound stoped working after upgrading Ubuntu 14.04.6 LTS.
I checked Alsamixer but I could't open it. I tryed to reinstall pulse audio
and Alsa but yet, Alsamixer doesn't open.
I'm getting the following error message when I try to open Alsamixer:
