Hi All, Following the suggestion from Uwe concerning this line in Audio/soundout.cpp
void SoundOutput::stop () { if (m_stream) { m_stream->reset (); m_stream->stop (); } m_stream.reset (); // <------- dropping this reset makes problem go away } I deleted this line and rebuilt wsjtx-2.7.0-rc6 on Monterey 12.7.6 and invited an OM to download this and try it on Sequoia with this result, as previously confirmed by Arkadiusz: — We have a winner! Everything is working just as expected. I Tuned and then completed a QSO. — — John G4KLA _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
