[Elecraft] K3s USB built in sound card

[Joe Subich, W4TV]

Wes,

What version of Windows?  Some older Windows drivers (USBAUDIO.SYS)
set an inappropriate range for the attenuator/gain sliders with some 
CODECs in the PCM-290x family.

Open the Windows Control Panel | Sound, select the Playback tab, USB
Audio CODEC -> Levels, right click on the slider and select dB.  Then
make sure the range is 0 to - 128 dB.  Also Select the "Enhancements"
tab and *uncheck* all of the "Enhancements" (particularly Bass Boost
and Loudness Equalization).

73,

    ... Joe, W4TV
