[wdmaudiodev] Re: How to make Recording icons not appear for a device in the Sound panel

From some other forum posts, it appears that in addition to the mods below I
made in the PHYSICALCONNECTIONTABLE: I also need to
PHYSICALCONNECTIONTABLE TopologyPhysicalConnections =
{
KSPIN_TOPO_WAVEOUT_SOURCE, // TopologyIn
(ULONG)-1, // TopologyOut
(ULONG)-1, // WaveIn
KSPIN_WAVE_RENDER_SOURCE // WaveOut
};
.. that I also need to mod wavetable.h to strip out the recording pin
declarations.
However any changes I’ve tried to make that fail are causing the Playback icon
not to appear, which doesn’t surprise me as my understanding of that file is
minimal.
I pasted the wavtable.h file below, can anyone make suggestions on the correct
way to modify it to allow the Playback functionality to remain but the Record
functionality to no longer be displayed in the Sound panel?
Thanks,
Paul
