K3S internal USB sound card seen as microphone since new Win10 release ?

VE2TZT
Hi,

It looks like since a recent windows 10 release that my Elecraft K3S USB
Audio Codec input is seen as a "microphone" not as a "line in".

The result is that it is not any longer stereo but mono.

The default USB audio driver seems to be missing to give win 10 the necessary info to force a line-in installation and win 10 installs it as a microphone.

Any fix ?

Yes, change it to Stereo using Windows.  I posted this to
https://groups.io/g/Elecraft-K3/message/29258 on March 31st, but I'll
repeat it here:

To change the K3 USB sound card to Stereo mode:

   1. Right click on the Speaker Icon in the Windows Notification Area
   (lower right corner of task bar, near the clock)
   2. Select Recording Devices
   3. Click to select the USB Audio CODEC for the K3 (you may have more
   than one of these)
   4. Click Properties
   5. (optional) On the General tab, above the Change Icon button, you can
   give the K3 USB Audio CODEC a new name like K3 USB AUDIO
   6. Select the Advanced tab
   7. Change the sample rate to 2 channel, 16 bit, 44100 Hz (CD Quality)
   8. Click Apply
