=== Linux OSS driver ===
On systems where lspci shows an Intel AC'97 Audio Controller, this chip is supported by the i810_audio kernel module.

=== Linux ALSA driver ===
On systems where lspci shows an Intel AC'97 Audio Controller, this chip is supported by the snd-intel8x0 kernel module.

On systems where lspci shows an ATI AC'97 Audio Controller (R40e and R51e), this chip is supported by the snd-atiixp kernel module.

==== Note ====
On some models ({{T40}}, {{T43p}}, ...) audio is muted if either Headphone or Line Jack are unmuted. See also ALSA Wiki FAQ [http://alsa.opensrc.org/FAQ004]. Also, if Headphone Sense or Line Jack Sense are unmuted audio is dead ({{R52}}). By default the Sense settings are not shown in GNOME.

=== FreeBSD OSS driver ===
snd_ich will work happily for this audio chip.
