[Elecraft] K3 Codecs and Remote Desktop

[Ron D'Eau Claire]

Jack, did you check for proper operation of the speaker and phones logic as
described in the update instructions:

.	Hold CONFIG to enter the configuration menu and turn B (VFO B) to
locate SPKR+PH on the LCD. 

.	Turn the   A (VFO A) knob so no is displayed on the LCD.

.	Check to see if audio is present in the speaker with phones
unplugged.  If not tap the 1 switch on the keypad until you see PH.R SW - on
the LCD (be sure the - sign is displayed at the end). This is the default
setting required with the KIO3B installed that restores normal operation;
Selecting no will silence the speaker when phones are plugged in and if yES
is selected both phones and speaker will be active at the same time.

Subject: [Elecraft] K3 Codecs and Remote Desktop

After installing the KIO3B, I had no problem passing audio to and from my W7
PC.  The speaker and microphone codec appear in the Sound Control panel. 
When I try to use Remote desktop, the codecs a are gone and there's no sound
on my Dell laptop.  When I check the Sound Control the only sound device
that appears in the Playback tab is a Speaker and the Recording tab is
blank.    When I check "Play on remote computer"  and launch RDT, The Sound
Control shows the K3 codecs and I can hear sound on the host computer.  

Before I launched RDT, at the Local Resources tab/Settings I checked "Play
on this computer".  Here's my conundrum.  For a pan-adapter, I use an SDR-14
software defined receiver from RF-Space.  The Spectra-Vue software is
compatible with the K3.  I feeds off the K3's IF and it functions like the
P3 except the spectrum display is on the PC monitor.   Within the span it
can also serve as a 2nd or 3rd receiver and the audio from each demodulator
is fed separately to each speaker.   When I use Remote Desktop the audio is
passed to my Laptop and when I click on the Taskbar-Speaker icon, the
Spectra-Vue volume control is shown.   

My question is "What is the difference between the Spectra-Vue codec and the
K3 codac?   Why is the audio available on the SDR-14 but not on the K3.
