Hi Matt - thanks.

Looks like I am ONLY loading:

But I dont think the res_timing(x) is working on CentOS 5.
res_timing_timerfd does not
even seem to be compiled on this box.

How do I tell for sure what its using and if its good. All I saw in the
asterisk log was the
two res_timing_pthread and res_timing_dadhi being loaded.

Everything else is fine actually. It worked with the card, and withthout
the card just sending audio to
one endpoint has audio issues in a conference. The machine is doing nothign
else at that time.
