K3S - Win 10 Pro USB Audio Codec Issue

My radio club just replaced our pc's and we are now running Win10 Pro. The
K3S is recognized (com port and USB Controller) and works well with N1MM,
HRD and WSJT-X (CAT control). However, the USB Audio Codec is not being
loaded for the radio. Windows does not recognize the K3S sound card and as
a result, WSJT-X does not have USB codec options in the audio settings. I
have done a Windows reset / reload and downloaded the latest FTDI drivers.
We had no issue running the K3S via USB under Win 10 basic on our old pc's.
(K3S is configured correctly - Rs232 = 'USB' and Mic Set = 'line in'.)

I know this was an issue earlier this year when MS pushed out a Win10
update. I have searched the forums, but have not seen any fixes other than
what I have already tried. Does anyone have a suggestion as to how to get
the USB Audio Codec to load in the Win 10 Pro 'device manager - sound,
video and game controllers'?

Thanks.

Re: K3S - Win 10 Pro USB Audio Codec Issue

The FTDI drivers have nothing to do with the audio interface. Look in
device manager and see what you have under audio devices. If you find
some undefined devices, right-click, select driver, and click update.
If you need better step-by-step directions, I'd be happy to send you
very detailed instructions with screen shots. Also, make sure you're
selecting the right audio devices. Most PCs these day already have two.
With the K3S you're going to have 3.

Re: K3S - Win 10 Pro USB Audio Codec Issue

Thanks Doug,
I'll check the 'audio inputs and outputs' list again. If I remember
correctly, it only showed the internal sound card -mic and
speakers/headphone, no reference to the K3s or other USB Audio Codec.

Marty,

Have you tried unplugging the USB cable, then plugging it back in.
Windows should recognize and activate the USB Audio CODEC.
Also make sure "Show Hidden Devices" is checked.

Re: K3S - Win 10 Pro USB Audio Codec Issue

Thanks to everyone for your suggestions, I tried them all. After additional
sluething, I believe our K3S has an issue with the KIO3B board. The USB
Audio CODEC will not load or be recognized on any computer (CAT control
works fine and is recognized in the Elecraft K3 utility).

Additional testing: I tested other devices on our club PC. It quickly
recognized the USB Audio CODEC for an IC7300 and mini external sound card.
I then tried my personal K3S....and it quickly recognized both the USB VCP
and the Audio CODEC. Next I attached the club K3S to my personal PC - same
result as with the club PC, it was not recognized on my computer either.

I then tried reloading the firmware (again). No change. My conclusion is
that there is an issue with our club K3S.

I will have to call Elecraft support to see if there is a way to address the
USB audio CODEC or if the KIO3B must be replaced.

Re: K3S - Win 10 Pro USB Audio Codec Issue

You might want to wait until after New Year's day to make that call.
All Elecraft folks in Watsonville will be off until after Christmas with
only a skeleton staff returning for the later part of the week, then off
again until after New Year's.
