Perhaps you should try the AX.25-HOWTO first.

Well, what kind is your soundcard? Notice that the kernel 
soundmodem (the module you're trying) only supports Sound 
Blaster o Windows Sound System compatible cards. Many new 
cards are not suported by it.

But haven't you heard about the userspace soundmodem? It is 
not a kernel module, it's a usermode program, it's easier to 
configure, and (the most important thing) it handles the 
soundcard through OSS, so it works with virtualy every 
soundcard supported by OSS.

It's likely that your onboard soundcard will not work at all 
with the kernel soundmodem.

Try usermode soundmodem, and tell us.
