First off, my recommendation is for you to contact Digium technical 
support.  They will be able to help you triage and resolve this.

That being said, some questions that come to mind looking at your 
description:

1) Is the one-way audio constant or intermittent?  Does it affect all 
calls through the card or only "outbound routes"?

2) Do you have a VPM module installed on the card?  If so, does loading 
the card with "modprobe wctdm24xxp vpmsupport=0" change the behavior at all?

3) Is there anything strange you see in the output of the "dmesg" command?

4) Are you able to install and try the current trunk of DAHDI?  Does 
that change what you see?

Cheers,
Shaun
