Fxotune - tdm04b

Recently grabbed the new source from cvs-head and rebuilt to the newest version of asterisk. I have brand new TDM04b cards and was hoping to use fxotune to fix my severe echo problem. However, even though fxotune compiles, wctdm won’t? My understanding is that I need to have this new wctdm module loaded? Help? :smile:

Do I need to fresh install linux and download/install from scratch?
