=== The latest stable ALSA - simplest ===

Whenever a stable release of ALSA is released, the linux-backports-modules-alsa-[Ubuntu Release]-[Kernel Flavor] is updated. [Ubuntu-release] means "karmic", "lucid", "maverick" etc, and [Kernel Flavor] normally means "generic" (or "server" for Ubuntu server edition). So just download and install this package, reboot, and test. /* === The latest stable ALSA - simplest ===

Every night the current ALSA snapshot is taken and built on Launchpad by the [[https://launchpad.net/~ubuntu-audio-dev|Ubuntu Audio Developers Team]]. This will give you the absolute latest. See [[Audio/InstallingLinuxAlsaDriverModules|this link]] for how to install them.

=== DKMS ===

As a third option, DKMS packages can be constructed that automatically rebuilds themselves whenever a new kernel is installed. More information to come.

Sometimes upgrading sound drivers will help you fix an issue with your sound. There are several ways to upgrade your ALSA sound drivers.
