[Asterisk-Users] Terrible crackling on analogue line and X100P card

[dean collins]

I have a similar situation but it seems to vary from call to call
sometimes.

Using 2 digium genuine x100p's in a dell with riser card.

I'm wondering if it is something to do with the riser because it doesn't
seem to matter if I swap various cords, positions, etc.


Cheers,
Dean
