The APO flags exist in two places for each APO module:
1) In the code, as you have noticed – here’s the SysVad LFX flags
, (APO_FLAG)( APO_FLAG_SAMPLESPERFRAME_MUST_MATCH |
APO_FLAG_FRAMESPERSECOND_MUST_MATCH |
APO_FLAG_BITSPERSAMPLE_MUST_MATCH | APO_FLAG_INPLACE)
2) In the APO registration in the .inf – here’s the corresponding snippet
from sysvad.inf
HKCR,AudioEngine\AudioProcessingObjects\%FX_STREAM_CLSID%, "Flags", 0x00010001,
0x0000000d
Make sure both locations match.

Subject: [wdmaudiodev] APO_FLAG_INPLACE weirdness
I have GFX and LFX modules running for windows7 (x64). Both modules have the
following flags defined
(APO_FLAG_FRAMESPERSECOND_MUST_MATCH |
APO_FLAG_BITSPERSAMPLE_MUST_MATCH |
APO_FLAG_SAMPLESPERFRAME_MUST_MATCH |
APO_FLAG_INPLACE)
Audio is played back just fine and my trace looks like this

If I remove APO_FLAG_INPLACE from the LFX module and that is the only change
made to the code then audio is not played back. I get the following error
message "Error while opening sound device.
Please check the output device settings and the project sample rate.". I use
Audacity to play back the audio.
Now my trace looks like below. Obviously something is wrong. I don't understand
what the problem is. Is it a bug in my code? Is removal of APO_FLAG_INPLACE
unsupported?
What strikes me is that the system does not even call
ValidateAndCacheConnectionInfo() on the LFX module after APO_FLAG_INPLACE is
removed. And even though the system has a problem with the LFX module why can't
the system just use the GFX module.
