One for Matthew I suspect.
tl;dr; I've assembled the ETL glitch trace package as detailed in the blog.
Where to send it?
WASAPI glitches badly with USB devices in exclusive mode. Win 10 1607 on a
gen4 4GHz i7 with Asus motherboard.
Changing the buffer sizes (according to the minimum and maximum values
returned by GetDevicePeriod()) has no effect. Tested on 2 USB full speed
devices, an ancient Roland adapter and a much newer Behringer based on a TI
chipset.
Shared mode is AOK.
using the onboard Realtek HDA in _exclusive_ mode is also AOK.
Results are identical using whatever the latest developer release might be.
Some scope images attached for anyone interested.
TAIA
Jerry.
