WSJT-X and JS8Call lose audio output after the first call

Don_N5SKT Member ✭✭

I have just upgraded to 3,2.24 and am experiencing an odd issue. When I transmit with WSJT-X, I get audio out to the radio but time the radio is keyed, there is no audio to the radio. There was also a recent Windows 10 update installed before the upgrade. I have fixed it in WSJT-X by going to the audio setting and selecting another transmit device and then going back to the flex device. However. JS8Call does not get corrected by this. One heartbeat and no more output. JS8Call 2.2.0 and WSJT-X 2.2.3.

    Same problem with Win10 and JS8Call: runs some time, then audio output or input error, independent of soundcard and soundcardsettings.

    My workaround: changed qtaudio_windows.dll in c:\Program Files (x86)\js8call\plugins\audio\ to a newer version with 57856 Bytes which I found on a dll-website.

    After 10h with a HB every 10 min no audio output error encountered. Coding and Decoding seems to work fine with this dll (guess it's independend of the audio-output-input-dll).

    This is a strange problem. Jan's update is a very good clue and you'll see it is related to the Windows side of things.
