Hello,
Today, I compiled latest development/testing release of OSS4.1 (
http://www.4front-tech.com/developer/sources/testing/gpl/oss-v4.1-buildrc1-src-gpl.tar.bz2)
and was able to install successfully, but without Headphone sensing.
Here is a one line patch that enables Headphone Jacksense support for
AD1981B sound chipset.
I tested it with my HP nx8220(has AD1981B) laptop, and works fine. Don't
know if it will work with AD1981 and AD1985.
Sorry for my simple english.
Hope it helps.
Hüseyin
