I am looking for generic device drivers for Soundmax Audio Codec AD1981B for:
WXP, WIN7, WIN8 32/64 bit for my applications.
Please note: the AD1981B is obsolete (last time buy until Nov 2009), see note
on AD198B web page. We have no replacements for this device as Analog Devices
PC audio codecs business has been transferred to Conexant since 2009. For
possible alternatives to this device, please contact Conexant. See Conexant web
NOTE : Regarding drivers:
Analog Devices does not manufacture sound or modem cards. Many sound cards use
chipsets from Analog Devices in their designs. Please try the PC manufacturer
or the maker of the Motherboard (if the sound chip is integrated onto the
Drivers are often customized to work with specific PCs or motherboard platform.
Please contact the manufacturer of the PC for technical assistance. For
technical assistance on a specific sound card, please contact the manufacturer
of the card.
Other sources you can check:
* You can visit the FCC's web site and use the search engine to see who
manufactured the card.
* You may also be able to locate & download drivers for these cards at the
following web site:
is extremely good You have to register (once) but
it is very useful and free.
