[Asterisk-Users] Audio Problem when zaptel modules are loaded

[Matthew T. O'Connor]

Hello, I have an Asterisk @ Home box up and running.  I'm trying to 
prepare the box to be the phone system in our new office.

I have 3 Polycom 500's with the latest SIP firmware and all is fine, I 
can call Asterisk, check my voicemail, call the other handsets, transfer 
call, even make calls to the PSTN via voipjet.  So I'm doing ok.  The 
problem I have now is that when I reboot into a kernel that has the 
zaptel modules compiled for it, then I can no longer call asterisk 
server and hear anything.  I can however still call the PSTN via voipjet 
and I can call the other phones.

When you look at the * log output below the only thing that I see as 
potentially relevant  is the fact that when I can't hear the vm-login, 
there is a "Scheduling timer at 160 sample intervals" just before it, 
but when it works, there is not. 

Any ideas?  Thanks,

Matt

      This first log excerpt is when I boot into a linux kernel that has
      the zaptel drivers installed, this results in asterisk not being
      able to play sound to me, so I can't hear the vm-login recording.

      This next excerpt is from a different kernel on the same box that
      doesn't have the zaptel driver compiled, here the sound works

      Why would the zaptel drivers effeect this?
