Hello. I am experiencing exactly the same issues as AJK47. I will not post the LatencyMon data as they are identical, using the same NIC/drivers, Win 7 64bit, x79. I too have adjusted as many settings as are available, power options, etc to no avail.
While AJK47 uses USB audio, I can confirm the problem is not USBaudio exclusive but also with PCI pro level ASIO sound card from RME via multichannel ADAT. These cards are industry standard and specifically manufactured for professional near zero latency audio recording. They are not toys.I am used to 32-64 buffer multitrack recording/playback without a glitch
While this audio workstation (used in a pro studio) usually remains offline there are several applications requiring online authorization upon launch thus internet access, however briefly, is essential even on a majority offline machine. Disabling the driver solves the problem but I just cannot go back and forth to device manager 2 or three times simply to launch my DAW and multiple plugins.
The current Intel drivers render the audio engine useless while they are active.
Thanks.
