=== AD1981HD ===<br />
This is a Analog Devices High-Definition Audio 1.0 controller<br />
<br />
=== Features ===<br />
* Chipset: AD1981HD<br />
* Interface: HD Audio 1.0<br />

<br />
=== Linux ALSA driver ===<br />
==== Installation on Debian GNU/Linux ====<br />
The AD1981HD installs by default in Debian. To get it to work type 'alsaconf' on the command line as the root user.<br />
<br />
{{ cmdroot| alsaconf }}<br />
{{HINT|To become root, type su at the command line.}}<br />
==== Problems ====<br />
* As of kernel 2.6.17, some users report a missing master volume control (e.g., with the T60p and Z60m), as described in this thread: http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg17089.html<br />
: As of ALSA 1.0.13 the master volume has returned. Download the latest modules from your distrobution to fix this problem. Otherwise as a temporary fix add model=hp to the snd-hda-intel module option. This will return the master volume control to your control.<br />
{{HINT|If you use Debian, edit /etc/modprobe.d/sound to change ALSA module options. }}<br />
* If you experience crackling noises, this can be avoided by adding the position_fix=2 optional argument for the module.<br />
<br />
* If you have problems recording audio, try selecting "Front Mic" as the capture device.<br />
{{ NOTE | There have been reported problems using arecord while debugging, it's recommended to instead use Audacity. }}<br />
<br />
* According to a bug in the BIOS, the modem disables the audio device too. If you are having problems with your soundcard and have disabled your modem, try re-enabling it. On some systems disabling the modem results in fixing some problems, so if you haven't disabled the modem, try it. On the T60p model, the in-kernel ALSA system will report "azx_get_response timeout"; re-enabling the modem fixed this issue and brought audio back.<br />
<br />
* external / internal microphone does not work for me. see <br />

https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2736<br />
(different laptops but same sound chip)<br />
<br />
{{NOTE | This problem was fixed for me by specifying the model option to 'ref' for the snd-hda-intel module (see first problem). }}<br />
