[Dx4win] PSK-31 Transmit Set-up

[Bud Governale]

Thanks to  Paul KK4HD and others I have PSK-31 able to receive and display stations and also key the K3 into transmit.

However, I’m not out of the woods yet.

PSK-31 keys the K3 and is sending a selected macro. I can see in the waterfall the macro being sent and the K3 is in transmit but no audio is being sent to the K3 which is in USB mode. Wattmeter shows zero watts out.

Using N1MM I can send and transmit prerecorded wave files to the K3. The outbound audio path from the sound card to the K3 is working.
Also I can watch the Windows-7 Sound window and see in Playback tab the Realtek Digital output displaying sound bars when PSK-31 is in transmit.

The DX4WIN Control tab shows Output selection is Realtek Digital Output. N1MM has the same selection for transmitting WAV files to the K3.
I hear no audio from the speaker of the problem desktop.   

Any help would be much appreciated.
