Workaround to no audio on startup on Win 10 for IC-705

Latest follow-up on my experience…

I was able to get PortAudio audio system working with VB AudioCable when launching wfview weekly build 20221001-11-24-08. VB Audio Cable was 4th in the audio output pull-down list, so that got me thinking if the problem happened only for the 1st entry in the pull-down list. I describe an experiment below. Interesting results - always a problem when launching wfview with the first item in the Audio Output list for each Audio System.

This behavior is reproducible for me, so I hope it is for others, too, to identify and resolve the problem.

Best,

Ron

  • Disconnect, select VB Audio Cable, reconnect - audio output works.
  • Disconnect, select Realtek Speaker, save settings, exit wfview
  • Launch wfview - audio works
  • Disconnect, select VB Audio Cable, reconnect - audio output works.

PortAudio (continue in same session above)

  • Disconnect, select PortAudio as Audio System.

  • Many items in Audio Output pull-down list

    • Microsoft Sound Mapper is first
    • Cable Input (VB Audio Virtual Cable) is fourth
  • Select Microsoft Sound Mapper, save settings, exit wfview. (Log 1)
