Sounds like RFI if your USB audio is dropping and comes back on restart of 
WSJTX.Do you have chokes on your USB cable?What rig are you using?What does 
your shack grounding look like?

I can supply some screen shots of my radio.

I have a third behaviour. My trick of tripping Halt and Enable also sometimes 
fails to bring the audio back. Tx still occurs but no audio is passing.

If I exit WSJT-X and restart it, audio returns to the Tx.

Subject: [wsjt-devel] 2.6.0 RC and HamRadioDeluxe Radio issue

  

I notice there is a beta RC 2.6.0 out and I am trying it because it mentions 
the HamRadioDeluxe rig control. I certainly notice an issue with the 
HamRadioDeluxe rig control and it's not solved for me with 2.6.0 RC

  

I am using IC-7300 and HamRadioDeluxe radio set in WSJT-X and the latest 
HamRadioDeluxe software. It works fine about 70% of the time. But it often 
jumps into a mode where Tx power drops and no audio is output. Sometimes there 
is audio but the sig output is a vague USB transmission about 1.5-2k wide (up 
from the ref frequency). All other rig control functions using the HRD Rig 
Control interface work fine with my IC-7300 radio.

  

I can fix it sometimes by clicking Halt TX followed by about 1 sec, then click 
Enable Tx and it goes back to normal. Sometimes this technique fails and I have 
to exit WSJT-X and restart it. It works fine for a while again.

  

If I just go direct via com port 6 I never have the issue. But that means 
exiting HRD rig control each time and I certainly like opening WSJT-X with one 
click rather than the scramble required to disconnect and reconnect etc. Plus 
the logging and multi-casting is important to me as well to use GridTracker.
