Bug#759757: downgrade helps

[積丹尼 Dan Jacobson]

OK this works:
     Downgrade the following packages:
1)     libpulse-mainloop-glib0 [5.0-10 (experimental, now) -> 5.0-6 (unstable)]
2)     libpulse0 [5.0-10 (now) -> 5.0-6 (unstable)]
3)     libpulsedsp [5.0-10 (experimental, now) -> 5.0-6 (unstable)]
4)     pulseaudio [5.0-10 (experimental, now) -> 5.0-6 (unstable)]
5)     pulseaudio-utils [5.0-10 (experimental, now) -> 5.0-6 (unstable)]
