Just a thought (128 rings a bell)... Intel HDA audio seems to be limited 
to -p128 at -n2 or -p64 at -n3. Jack will not even start for me lower than 
that with them (I have two). Also  if pulse is running... It can limit 
other cards to the same latency as an internal card has. Best to turn off 
internal cards in bios. I have found that even when they are turned off in 
pulse, a jack event can turn them back on.

The way pulse works with jackd can be very useful, but it has issues. The 
user needs to be aware of them all.
