Sound Cards

Ubuntu supports a wide variety of sound hardware and software. Two models of sound card drivers compete for prominence in today's market:

• ALSA, the Advanced Linux Sound Architecture, which is entirely open source

• OSS, the Open Sound System, which offers free and commercial drivers

Ubuntu uses ALSA because ALSA is the sound architecture for the 2.6 series kernels.

ALSA supports a long list of sound cards. You can review the list at If your sound card is not supported, it might be supported in the commercial version of OSS. You can download a trial version of commercial software and test your sound card at

Ubuntu detects most sound cards during the original installation. If you add or replace a sound card after the initial install, Ubuntu will automatically detect and configure it at the next reboot.
