Yes, I was opening a stream before running wave test by playing a song from
WMP. So after i tried running wave test without first opening a stream. But
still there are failures which i mentioned in last mail.
I just saw on KS studio and found that it reports Current Count = 0 and
Possible Count = 1 for KSPROPERTY_PIN_CINSTANCES.
Should i attach my wave test log file?
Thanks.
