Very high likelihood that they are Intel-specific. I bet your Intel
audio and video share an interrupt, either with each other or with
something else (like built-in wireless) ... It's no consolation, but the
Intel hardware in my Toshiba laptop gives me xruns when the display is
updated.

Folk on the list have posted various command lines to see what hardware
is using what interrupts. I don't remember what they were, sorry.
