I need to display speaker connection status in a portcls audio driver. To
begin I have modified audio/msvad/simple code in the DDK 6000. But the jack
is not displayed on the audio panel and the KsStudio does not show the
KSPROPERTY_JACK_DESCRIPTION when the driver is instantiated. The code is
below.
Any help or code sample would be appreciated.
Thanks,
Nikolay
