K3s USB audio problem; both channels identical

Hi Elecrafters,

I found out that I lost the audio of the MAIN RX on the USB port of my K3s
(with SUB RX installed)

On all other audio outputs (speaker, headphone, line-out) MAIN and SUB audio
are present.

On the USB port the Right and Left audio stream are identical. (so both L
and R is MAIN audio now)

I did check on new firmware and I did an MCU LD with all the latest versions
available. (which were already loaded anyway)

The USB problem was still there.

Once again an MCU LD.

The audio via USB is still only MAIN (at both channels), no SUB audio.

An EE INIT with some older configurations.

This should not have any impact and it didn't; no change.

CAT is working OK via USB.

Different cables make no difference (as expected).

Changing L-MIX-R to different settings makes no difference (as expected)

Besides USB, power and antenna nothing else is connected to the K3s.

After some K3s power cycles the reverse is now happening.

USB audio is only SUB audio (both R and L channel) and no MAIN audio is
present

The rest of the audio outputs remains OK.

I did check USB audio on 2 different PC's (both WIN10) with various audio
programs which are using Right and/or Left channel audio input (WSJT-X,
MSHV, Visual Analyser).

All have the same issue.

Windows 10 settings are OK, mic. input is set for 2 channels.

There are no other programs running, requiring audio input.

Visual examination of the KIO3B boards revealed nothing.

Anyone with some bright ideas that could help me out?

PS: I did sent a mail to Elecraft support, but hope to get some feedback
from this group as well.

Thank Microsoft!

In Windows Sound Control Panel (You may need to access it via
Settings -> System -> Sound -> Related Settings)

Select the Recording tab
Select (double click) Line for USB Audio CODEC in the K3
Select the *Advanced* tab
Set the Default Format to "2 channel, 16 bit, 48000 Hz"
(48 KHz is required for digital applications like WSJTX)
Click "Apply"

73,

Re: K3s USB audio problem; both channels identical

In reply to this post by hdv

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.

So now I have to figure out what went wrong and why. (and why 2 PC's fooled
me in the first place.)

Sorry for the bandwidth, disregard my previous mail.

Re: 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
