I hear nothing connecting to the input line. It is not a driver problem since that works. When I swap the input line with the speaker the speaker always works. The softrock goes into TX mode and transmits if I use the audio test on the PC to send sound to that output.
Sorry I do not think I understand.
Somehow HSDR is sending the signal to the wrong device, though I can't tell which one.
I have never known HDSDR to send audio to the wrong device unless I myself have set it to the wrong device.
Device descriptions in the drop-down can be confusing. Rename them in the Sound Control Panel if that will help.
And you are certain your audio settings in Windows are correct?
