Every now and then, on transmit, my sound suddenly switches to speaker and not to the rig.  I happens randomly and I have to restart WSJT-X.  It always happens at the most critical moments when I'm working a new DXCC.  Anyone else having this issue and is there a solution?

OM,

which version of WSJT-X are you using? What rig do you have? How is your rig connected to your PC for audio? Which operating system are you running WSJT-X on? Do you get any error messages when this happens?

Hi!
Thank you for the very fast response.
I am using WSJX version 2.2.2. My rig is Yaesu FT-450D.  My rig is connected via the Yaesu SCU-17 USB interface. My operating System is Mac OSX Catalina v 10.15.7.  No error messages at all.  I'll be quite happily playing on WSJT-X, la-la-la-la-la, happy happy, then suddenly, sound comes out the speaker.  Have to restart WSJT-X and it goes away.  No warning, it just happens randomly.  I was wondering if anyone else experiences it and if there was a fix.

Austin,

My initial thought is – when random strange software behavior happens, in many cases it is RF getting into the computer.  Try reducing power, ferrite beads on cables, make sure there are no ground loops, etc, etc.

 

Just a thought.  Joe, K1YOW

I've got the ferrite beads on the USB cable.  Apart from that there is not much more I can do.  Maybe it is RF in the shack.  My situation is limited and I don't have much space.  I'm transmitting 50 watts maximum.    I will see if it happens when I go out portable to rule out proximity to the antenna.

Hi Austin,

this behaviour is common to some models of Macs, we don't have a definitive solution but many users have found that setting the USB Audio Codec devices to a default sample rate of 44100 Hz, in Audio Midi Setup, instead of the recommended 48000 Hz helps.

In years of operating WSJT-X, that has never happened to me. Sounds like an OS issue.

Yeah I agree. I think it's the sound card drivers suddenly resetting

Put the ferrite beads on ALL cables headed towards the computer...

Yep, that was already in place.  Already done.  It happens once in a while and random

Just turn the power down to zero.

windows or linux and is it an ICOM rig with built in USB audio/CAT bridge?

I used to have that problem on my Mac computers. From what I was able to determine, Apple changed something in the way they handle USB2. It is NOT an RFI problem. You can try the 44,000 baud setting, which will greatly help, but is not a cure-all. If you have a USB3 port, give that a try - it also seems to help. Another thing that worked 100 percent for me was to route your USB audio device through a USB to Thunderbolt adapter.

As stated above, it's none of that. It is a Yaesu FT450D, Yaesu SCU-17 interface and Mac OS Catalina.  The driver cannot be set to anything other than 48000, 48000 is the only option.

Hi Austin,

OK, try this. Create a new Aggregate Device in Audio MIDI Setup and assign your rig's audio codec to it, then change the WSJT-X "Preferences->Audio" to use that device. You can also give the new Aggregate Device a meaningful name like FT-450D if you wish.

OK thanks.  I've created an Aggregate Device and assigned Audio USB Codec to the Aggregate Device.  In WSJTX though, Aggregate Device is not an option.  Only USB Audio Codec.

Hi Austin,

with WSJT-X v2.2.2 you will need to restart WSJT-X to see the new audio devices.

Ok, thanks, I will try and see if I get disconnected from the rig again. It is intermittent and random which makes it hard to trace.

This happens to me almost daily.  I'm usually up early chasing FT8 DX on 80M and when I'm done I just leave WSJT-X up and come back for more in the late afternoon.  About 50% of the time, the audio out has been redirected to the PC speakers (that's the default audio output device).  100% of the time, restarting WSJT-X fixes the problem. There has been no other activity on the PC during the off time.   I'm running Windows 10 Home Edition at the latest maintenance level.  Using a microHam Digikeyer II as the interface with my FTDX-5000.  No RF problems in the shack - things are properly controlled with chokes.  Besides, there is NO RF generated during the period when the audio problem occurs.  I've been experimenting with JTDX recently and have not yet had the problem occur with it.

It sounds as if your computer is going to sleep while not being
used which turns off the external sound card forcing audio back
to the internal sound card.

*DISABLE* Sleep/Hibernate and use the Windows Power Options to
disable USB Selective Suspend.
