Your x100p card is on interrupt 9 by itself (not shared with any other i/o device). That's a good thing. Those two items rule out a number of items in terms of what might be causing the crackling noise. What * version are you using Dean? Have you tried other versions?

Have you tried other versions? >[DC] I use Asterisk@home V 0.8 [DC] this has been an ongoing problem so not sure if it is related to version (as I've used asterisk head up until about 6 months ago and version 0.4,0.6 and now 0.8 version of A@H [DC] Cheers, Dean
