Hi Keith, your reply above was to Ulde IK2TYL's comments not mine although I did suggest that his proposed test was a good thing to try. The loss of Rx audio at the same time as Tx audio is an interesting data point. What I assume is happening is that both the speaker and mic/line in audio devices are being reset or switched spontaneously. I am fairly certain this behaviour is not due to anything we do in WSJT-X or even that the Qt framework we use for audio, this dual effect is consistent with that since at the level that Qt and hence WSJT-X interacts with the audio devices they are separate and apparently unrelated. Only at the lower levels of the Mac OS X Core Audio services or the device driver are the two audio devices tied to a single physical device. The logical conclusion is that there is nothing we can do until the driver or operating system authors sort out whatever the issue is. This needs more users to report the issue to SiLabs and Apple. I also suggest that fldigi users get involved as well as I gather it suffers the same problem. 73 Bill G4WJS. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ wsjt-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/wsjt-devel
