It won't compile in VS2017, and the retargeting extension also won't install
over VS2017. Is there a link to updated sample?

Is the "disable all enhancements" checkbox in question on the Advanced tab
or on an audio-driver-provided enhancements tab?

 

If it's on the Advanced tab, it controls the
PKEY_AudioEndpoint_Disable_SysFx property.

disable-sysfx

 

If it's on an audio-driver-provided enhancements tab, then the checkbox does
whatever the audio driver author wants it to do - hopefully this is also to
control the PKEY_AudioEndpoint_Disable_SysFx property.

 

Some audio processing is so essential that to turn it off risks physical
damage to the system it's running on. In particular, if an APO advertises
that it performs speaker protection, we won't disable it, even if the
property is set.

 

You can run the Audio effects discovery sample or audio effects discovery
HLK tests to see what effects are provided.

Hi!

In my experiments I've found that "Disable all enhancements" checkbox
in sound device property page doesn't influence loading of EFX APO,
so it is still gets loaded by audio subsystem.

Is this by design or a bug?

OS is Windows 10 with updates.

regards,
Artem
