AD1981B

This is a Analog Devices AC'97 Audio controller

Note: The documentation of the R40 incorrectly(?) states it has a AD1891A

Features

  • Chipset: AD1981B
  • Interface: AC'97

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, ... R51e ...) audio is muted if either Headphone or Line Jack are unmuted. See also ALSA Wiki FAQ [1]. 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.

ThinkPads this chip may be found in
