I am also using an external usb sound dongle (the $5 variety from Amazon). I am not seeing any of the noted audio issues with the 64 bit version.
I have set the audio once, gone back and forth, started, stopped the program, changed configs. I don't see it. I assumed it was because it was not the motherboard sound card. Now I gather from Bill that it is because it has no level setting. BTW, I assume we are talking about transmit level setting, not rx? 73, N0AN Hasan On Tue, Apr 30, 2019 at 3:35 PM Bill Somerville <g4...@classdesign.com> wrote: > On 30/04/2019 21:03, Neil Zampella wrote: > > > > FWIW ..
