Hello,
I am working on a virtual audio driver which is based on WaveCyclic.During
KS Position test my driver is failing with following error,
FAIL: Non-zero position is being reported, but the cursor is not moving!.
Test Case is: Standard Streaming\Rendering Performance Tests\Startup
Latency (standard streaming).
As per my understanding, KS Position test checks the behavior of
GetPosition function. But in case of this failure, i am failed to
understand what exactly this failure means and where should i look in my
driver code to solve this failure.
Can anyone please help me to understand this failure ?
During investigation, i got to know that during the transition from
KSSTATE_RUN to KSSTATE_PAUSE state, play position should get freeze and it
should unfreeze when transition from KSSTATE_PAUSE to KSSTATE_RUN happens.
But my driver was not doing like this, so i thought this might be reason
behind failure and i made changes in my driver code according to this. But
still failure remains.
Thanks.
