Update:

Pulseaudio has been integrated into upstream wine ebuild !!

Hence I removed wine from my overlay.

Gentoo still rocks!

During my journey from Ubuntu back to my beloved Gentoo Hardened I came across the fact that current upstream wine ebuilds do not allow to enable the existing wine pulseaudio patches.
These patches from Art Taylor have proven to be rock stable ( great work !!) , so I decided to make them accessible by adding the pulseaudio USE flag to the wine-9999.ebuild.

Either download the ebuild incl. all needed patches or use Quarks Overlay, e.g.

 git clone http://www.startux.de/git/quarks_gentoo_overlay/.git
