With my brand new motherboard Asus Maximus IX Hero and CPU Intel i7-7700, 3.6 GHz and fresh Windows 10 incl. Creators Update installation
when I listen e.g. to
and moving the mouse around, hover links, orange waveform, etc. I have min. 10 audio drop outs and crackles (on this one track) with my professional external audio interface Universal Audio Apollo Twin USB 3.0.
LatencyMon 6.5.1 reports this on my Asus PC:
When I connect the audio interface on my 3.5 year old laptop "Lenovo IdeaPad Y580 i7-3630QM" which has the same fresh Windows 10 installation and settings, I don't have any audio drop outs and "graphics" problems:
System info from my brand new Asus PC:
- OS: Windows 10 Pro, 64bit, Version 1703, 15063.413
- Motherboard: Asus Maximus IX Hero (latest BIOS 0906)
- CPU: Intel i7-7700, 3.6 GHz
- Intel Graphics 630 (Driver 22.214.171.12427)
- External Sound: Apollo Twin USB 3.0 (Driver 9.2)
(connected on one back USB 3.0 on Asus MB)
Of course I've also set and tried in BIOS various settings to avoid audio drop outs
- Intel speed Step => disabled
- Turbo Mode => disabled
- CPU C-States => disabled
- Intel Speed Shift => disabled
- CFG Lock => enabled
Also all possible performance settings in Windows 10 have been done which are recommended by various major music software & hardware companies.
I've also tried
- newer drivers which all didn't solve the problem. Because of another bug (https://communities.intel.com/thread/114464) I still use build 4627.
- the audio interface on USB ASMedia 3.1 and on PCIE/USB3 card Startech PEXUSB3S44V - no difference.
I've googled around and found another user with a very similar problem - near the same PC hardware as I'm using:
I've enabled Mouse Properties / Pointer Options / Display Pointer Trails (long) and it has reduced the amount of audio drop outs/crackles to 1-2 instead of 10. Unbelievable why this happens.
Of course it has nothing to do with the mouse driver - I've tried MS default and LogiTech SetPoint driver and the USB connector on all possible connections - no difference.
Finally I was able to avoid the latency problem:
The support from Universal Audio told me to use the new added feature "USB Safety Buffer" (in their latest driver 9.2) which is part of the "USB audio streaming protocol 2.0" which has been added to Windows Creators Update.
http://www.uaudio.com/media/support/downloads/Apollo_Software_Manual_USB_v92.pdf (search for "Safety Buffer").
I've increased the value from "Minimal" to "Small" and all audio crackles are away.

Also a very good article if someone is interested: http://allen-heath.helpserve.com/Knowledgebase/Article/View/1002/201/qu-windows-driver-understanding-and-troubleshooting
Finally - the latency problem with this Intel Graphics Driver still exists,
because as far as I understand the Intel graphics driver must return within a specified time (read links above) to MS Direct-x dxgkrnl.sys.
It can't be that on my brand new fast PC I'm having this problem but not on my old Lenovo laptop with same Windows 10 installation.
Other users don't have an expensive audio interface with a superb company like Universal Audio who are updating their drivers - e.g. Native Instruments doesn't support a Windows 10 driver for their Komplete 6 hardware until yet (the audio interface I'd before).
