Is this blocking an HCK submission? If not, can you wait for the Windows 8.1
RTM build?

Hello Tzung-Dar,
This is definitely a bug in portcls. I debugged this a couple of weeks ago
myself. I found that that this is related to the fact that portcls adds a
DSOUND datarange to the list of dataranges exposed by the miniport. In doing,
so it copies the attribute flag, but not the attribute itself (at least that is
my theory based on the debugger output). Therefore when KS sees the flag and
tries to do a match on the attribute, the attribute pointer is garbage and an
AV crash ensues (as you have seen).
I have already reported this to MS. They have agreed that it is an issue they
need to address.
Cheers,
DJ

Subject: [wdmaudiodev] KSATTRIBUTE in PortCls use MiniportWaveCyclic
Hi all:
Does any one know how to add KSATTRIBUTE support by use WaveCyclic. I fill
Flags field with KSDATARANGE_ATTRIBUTES. And append KSATTRIBUTE after
KSDATARANGE_AUDIO. The driver can load correctly. But when start to capture
audio, I got BSOD and dead in KS.sys. When modify my code to use WaveRT,
capture audio can run correctly with out BSOD.
Does this is bug in portcls or WaveCyclic can not support KSATTRIBUTE?
BR,
Tzung-Dar Tsai
