[Asterisk-bsd] Clicking noise on TDM400P

[Aaron Seelye]

As an update to further digging, I tried using the #4 channel on the card 
(different dsp just to rule out a defective one as well), and the clicking 
remained.  I changed the card out for a X100P that I had laying around, (I 
believe it's genuine digium, I can't guarantee it, relevant dmesg info 
below) and the clicking was gone, perfect call quality.  Now I'm just 
wondering if anyone else on the list has the TDM100P with FreeBSD 6.1-STABLE 
(source current as of May 18th).
