AD1984

AD1984 This is a Analog Devices High-Definition Audio controller Features Chipset: AD1984 Interface: HD Audio

Linux ALSA driver

This device isn't supported by current Alsa Driver [1] (as of May 25, 2007).

However, Takashi Iwai has added support to this device in Alsa development version [2]... Still have to wait to get it included in the Linux Kernel... Note: It is rather trivial too get this working in a standard kernel right now, It is only 3 patches on top of the stock 1.0.14 code:

• Fix Oops with AD1984 thinkpad model
• Fix AD1984 basic model
• Fix Thinkpad X61/T61 outputs

Alsa-Driver 1.0.14 added some support for this chip, but did not work on my T61; however, using the latest HG/Mercurial makes everything work. I created a Debian package for unstable/sid with the HG alsa that works for me, available at [3]. --Jello 15:31, 6 July 2007 (UTC)

Works with Kernel 2.6.22 and Alsa 1.0.14a --Schlodty 12:01, 21 July 2007 (UTC)

ATTENTION!

It's really necessary to leave the modem enabled in the BIOS or the intel_hda-driver will reutrn azx_get_response timeouts which will lead to a non-working soundchip. Got that information from a comment from: here --Gladiac 06:12, 24 July 2007 (UTC)
