Do all of the following:
1. Implement KSPROPERTY_JACK_DESCRIPTION2 and set
KSJACK_DESCRIPTION2.JackCapabilities to decry support for jack presence
detection – that is, set the bit in the JACKDESC2_PRESENCE_DETECT_CAPABILITY
location to 0
2. Set the KSPIN_DESCRIPTOR.Category to something less attractive than
KSNODETYPE_SPEAKER; ksmedia.h has a list of GUIDs, and the white paper linked
in the blog post has a prioritized list. KSNODETYPE_LINE_CONNECTOR comes to
mind as a possibility.
3. Implement KSPROPERTY_JACK_DESCRIPTION for completeness

Hi,
Thank you for direction.
All endpoints are Speaker.
I am not using both JackDescriptor and JackDescriptor2.
Everything is lower and unattractive to other drivers, except for
PKEY_Device_EnumeratorName, mine is ROOT, and other drivers are HDAUDIO.
Is that a problem? what else am I missing?
Thank you,

Subject: [wdmaudiodev] Disable automatic default device change while

Hi,
Is there any way in windows 10 to prevent virtual audio driver from being
default device only at installation not always?
As it is automatically selecting driver as default device on installation.
This problem I am facing in windows 10 only not other.
For installation i am using devcon.
