asterisk users - May 2003 - Wildcard X100P Choppy Sound and Chipmonk Recordings

Hello,

I recently purchased a Wildcard X100P FXO Card primarily as a learning tool 
and to provide myself with voicemail and a few other perks that are better 
than an answering machine.

I followed the setup in the FAQ, and it works, just not well. The sound is 
very choppy and staticy whenever a call is placed. Sometimes it clears up, 
and sometimes it degrades very badly.  I also recently tested recording 
voicemail using just the demo voicemail box 1234.  When I went to play back 
the WAV, I sounded like a Chipmonk and then it locked up XMMS.

I've read a number of messages about not running anything that might be 
hogging the PCI bus, so I quit X, shutdown all non-essential processes, and 
still no improvement at all.

I'm curious if anyone can possibly help me out? Some debugging information
is
provided below:

Output from dmesg pertaining to card:

Zapata Telephony Interface Registered on major 196
Found a Wildcard FXO: Wildcard X101P
Registered tone zone 0 (United States / North America)

The computer is an MSI 845E Max Motherboard with a Pentium 4 2.4GHz Northwood 
processor and 512 Megs of PC2100 DDR Memory, and a Radeon 7000 AGP Video 
Card.

I tried both Asterisk 0.4.0 and the lastest from CVS. I'm running Gentoo
Linux
although I compiled Zapata, Zaptel and Asterisk myself into 
/usr/local/asterisk to prevent my portage directories from being polluted.  

Thanks for any help anyone may be able to provide!

Are you perhaps running your text screen in frame buffer mode?
That mode eats a ton of interrupts and will cause exactly the
problem you've described.
