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

  • You need to reinstall the alsa-lib and alsa-utils packages, reinstall the current kernel (or update to a newer kernel), and remove the model=3stack line from the end of /etc/modprobe.d/alsa-base. (Somebody with knowledge of the Ubuntu package manager please write an answer.)

  • Ok thanks CL that fixed it, I think I am even getting better audio than before I did the downgrade. Probably because of kernel 3.9. I'll post an answer with the steps I took soon.

Please note that this is for a 64bit system.

Step one: Reinstall alsa-utils

sudo apt-get install alsa-utils --reinstall 

Step two: Download and install alsa-lib

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
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-raring/linux-headers-3.9.0-030900_3.9.0-030900.201304291257_all.deb   
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-raring/linux-image-3.9.0-030900-generic_3.9.0-030900.201304291257_amd64.deb
sudo dpkg -i *.deb
sudo update-grub

This will update your kernel to kernel 3.9 which does have some audio improvements.

Thanks to CL. for the info.
