0.14.26 and 0.15.1 will include the fix for pulseaudio under Ubuntu, I
am in the process of testing the packages before the release, so you can
find them here already:
http://xpra.org/beta/
(though if we can fix your chrome DPI issue quickly, I'll delay the
release to include this fix)

Chrome is generally problematic (client side decorations in general),
though we are working on improving that.
