Well,
Have some issues on Windows 7 / 64 bit and may get here some light on this
WASAPI issues:
1. Using a Lynx L22 PCI Card and latest drivers (also older drivers
releases): on WASAPI initialization I get an Error x8007007A, what is not
presented/listed on MS/WSAPAI initialize :
The used sample size/hhns is always hold below the 500ms level…
BTW: No issue on Win10 & Win10 Creator update!!
2. I use on the Exclusive Events an 1 second timeout timer to control the
message flow.
NOW using the RME ADI-2 Pro, the first event is given/fired approx. after 1.2
.. 1.5 seconds … Follow on events (after the first event) are always within the
1 second timeout.
The question rises is this a normal behavior on Win 7, while on Win 10 this has
not be seen yet. This would mean, the first event timeout should be somewhat
larger than the follow-on.
Best Regards
Hp. Widmer
