# Ubuntu – How to upgrade alsamixer in ubuntu 13

I resonantly ran a script which I thought would upgrade alsamixer, I think it downgraded it. Whatever it did I now get crackly sound. I now have alsamixer version 1.0.16. I have heard that there is a 1.0.27 version, how do I upgrade to this version of alsamixer?

Thanks,
Aaron

Step one: Reinstall alsa-utils

sudo apt-get install alsa-utils --reinstall


Here is a link to version 1.0.25-4(the stable version)

Extract the archive and run the following code in the extracted directory

./configure && make


Then

sudo make install


Step three: Update Kernel

I'm not sure if this is required but I did it anyway

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-raring/linux-headers-3.9.0-030900-generic_3.9.0-030900.201304291257_amd64.deb
