[Elecraft] {K3} Loss of audio while changing digital modes

[Bill Frantz]

I played in the ARRL RTTY Roundup today, using both RTTY and 
FT8. When I changed from FT8 to RTTY, I had to change the 
digital mode from DATA A to FSK D. (I run RUMlogNG in RTTY 
contests, and it does RTTY using the CAT interface.) Whenever I 
changed from DATA A to FSK D by pressing the buttons on the K3, 
I lost all the audio out on both the headphones and the internal 
K3S upgrade "sound card". The bypass was to change modes with 
the mode switch and change back.

Any ideas?
