[LAU] Intel-HDA sound issues

[J M Needham]

Hi,

I've got 3 periods per buffer, and as I sid everything used to be all fine 
and dandy. So it's either the upgraded ubuntu realtime kernel, some 
modules therein, latest jack, or the fact that my wife's had a baby 
that's caused the problems.

If anyone has settings that work with the Intel-HDA (kernel name, jack 
version, modules used) that would be much appreciated. Or if anyone's had 
a baby and that's caused their computer to misbehave.
