Re: [Elecraft] K3s USB audio problem; both channels identical
As a side note This problem usually is caused by the Windows updates. The update will change the audio codecs in your Windows Sound system. So check the settings after an update to make sure Windows did not change them again. It has happened to me more than times than I care to remember after a Win10 update Rich On 2/20/2021 10:30 AM, h...@kpnplanet.nl wrote: It was a Windows 10 problem after all. I did a complete new WIN10 install on a 3rd PC, just to be sure I was not taken things for granted. Presto. All was working OK now. Two instances of MSHV are both running, while on a separate USB audio channel. I clearly see the spectrum differences of MAIN and SUB in the waterfall.
