1.4 goes back to the working 2008 driver but includes newer UDAAPO and CtTele files, now i've verified these do work on Applications and games so any problems making them work are on your end and not the driver. perhaps you are trying to use it with an app that outputs via Xaudio, which automatically expands to multiple channels.
