[Asterisk-Users] Help! - Unintelligible prompts and music

[AHBLWEB]

I have set up a couple of test Asterisk servers and have never had a problem
with sound.

I've just done a fresh install on a dual 1GHZ PIII Asus box running Fedora
Core3 with the Digium PCI Dev kit and following all the various Core 3
How-To's. I can make calls ok but when any sound is sent from the Asterisk
box such as voice prompts and music on hold the sound is completely chopped
up in distorted spurts.

I've recompiled n times from scratch and can't seem to make any headway with
this.
