I may have been trying to push the latency too low or I was using the 
wrong plugins. I was recording the electric guitar direct and using 
plugins to make it sound amped. Very little on the vocals of anything save 
an aux out to a single reverb. I can't remember what else now.

However, the en/decoding of too many things at the same time was over the 
top. The best I could get with skype->pulse->jack->idjc->icecast and back 
along with mp3 files decoding to mix in was over 20ms and still not 
stable. This is what some people use as a radio studio for internet 
radio. The i5 I can set -p32 no problem. Lower latency makes it easier for 
a host to converse with someone on the "phone". Skype may not be the best, 
but lots of people have it... I don't think pulse was resampling, but it 
may have been from 48k to 48k, the mp3s seem to all be 44.1k but they are 
decoded straight to jack, so only one resample (as part of the decode?).

Have you tried turning "boost" and hyperthreading off in bios? But then 
the whole chipset may be different too.

I agree.

Yes, but often people would prefer to blame bad sound from their missuse 
on equipment than on themselves. Some people choose not to learn.
