Bug 6672 has been closed with the comment that the ebuild has updated on CVS, however the ebuild on CVS is 2 months old. Would you please reopen bug 6672. http://www.gentoo.org/cgi-bin/viewcvs.cgi/gentoo-x86/media-sound/emu10k1-audigy/
The update on the audigy drivers are still being tested until they work properly. There are still a few issues with the current update. I know, I have asked :) But I do believe bug 6672 should remain open until the updated ebuild does reach the public.
