MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs): 484,814251
Average measured interrupt to process latency (µs): 3,910788

Highest measured interrupt to DPC latency (µs): 451,964687
Average measured interrupt to DPC latency (µs): 0,976482


_________________________________________________________________________________________________________

Voici ce que dit dpc latency http://hpics.li/e313986
Despite of all my optimisations, still have bad signal for approx 1 min... Could it be because of intel speedstep (unfortunatly, i can't desactivate it in the bios)? Has anyone the same problem? Even with a very lightened win10 (only 37 process), still have the same problem...

[RoJeC]

Pretty sure this behaviour hasn't been reported by others in at least the last 5 yars (my time at the forum).
Warm up of a sound card doesn't make sence as it holds no tubes...

Your PC is way above specs for using audio.

You could try using the build in sound card to check what happens. If this works fine the deck and vinyl can be excluded. Best use Asio4all to test the sound card. And only use the 32bit version of Cross. Just to avoid any driver issue whatsoever.
Be sure to use the right phono/line settings (don't send line out to a phono in).
