Comment 43 for bug 1784485

If you want to compile the kernel with the sound patch, you can use my github as a ready to use official kernel with patch :

git clone https://github.com/VanVan/linux.git
sudo apt-get install build-essential initramfs-tools fakeroot debconf-utils dpkg-dev debhelper bin86 kernel-package

You can then compile the kernel and install it.
You can follow some tuto here https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel

There is a lot of other tuto for each distribution.

Then, the sound works well :)
