Looking at the differences between svolume_sse.c from pulseaudio 0.9.16 and the current one I noticed that those changes are only cosmetical - only a comment has changed. It does not make sense to try to patch that... But you can of course try the patch I posted in #19 and see if that works for you.
It is quite simple really. Assuming you... - keep your sources in /usr/src - downloaded the patch to your home directory - have not built pulseaudio before so there are no pulseaudio*.deb or libpulse*.deb packages in /usr/src ...it goes something like this: (first get the build dependencies:) sudo apt-get build-dep pulseaudio (now get the source:) cd /usr/src apt-get source pulseaudio (patch the source:) (cd whatever directory the source was installed to, currently pulseaudio-0.9.18 so...) cd pulseaudio-0.9.18 patch -p1 < ~/revert_svolume_mmx_to_known_good_version.patch (build the binary packages:) fakeroot dpkg-buildpackage -b (install pulseaudio and libpulse:) (while still in the pulseaudio source directory, directly after the build has finished:) sudo dpkg -i ../libpulse0_*.deb ../pulseaudio_*.deb As to how to test the new build depends on how you use it. If you run a sound-generating package like mplayer or totem it should be sufficient to kill any running pulseaudio daemon with: pulseaudio -k It should autostart the next time you start any sound-generating program... unless you have autospawn=no in your personal pulseaudio config of course... in that case you need to start it manually. If you run some sound-generating daemon like mpd you may need to restart that to make sure it starts a fresh copy of pulseaudio.
