Linux ALSA driver
Installation on Debian GNU/Linux
The AD1981HD installs by default in Debian. To get it to work type 'alsaconf' on the command line as the root user.
#  alsaconf 
Hint:
To become root, type su at the command line.
Problems
- 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
- As a temporary fix add model=hp to the snd-hda-intel module option. This will return the master volume control to your control.
Hint:
If you use Debian, edit /etc/modprobe.d/sound to change ALSA module options. 
- If you experience crackling noises, this can be avoided by adding the position_fix=2 optional argument for the module.
- If you have problems recording audio, try selecting "Front Mic" as the capture device.
NOTE!
 There have been reported problems using arecord while debugging, it's recommended to instead use Audacity. 
- 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.
