[Asterisk-Users] WCTDM-24xxp woes

[Barry King]

I'm having a related issue with "could not fill input buffer" and 
submitted this bug report:
http://bugs.digium.com/view.php?id=7264

Rather then fixing volume issues, though, I'm trying to fix major echo 
issues.  [The card used to work fine.  fxotune even fixed the echo the 
first time I tried it, but gets the error you've been getting since  
then (granted though I'm now using zaptel SVN instead of a patched 1.2.5).]

I'm at the point now where I either get fxotune working or buy a Sangoma 
card with hardware echo cancellation.
