Three issues with JTAlert Ver 2.15.3:
1) Same here - no audio. Changed sound devices - no audio. Checked microphone permissions - no audio. Ran troubleshooting diagnostics on audio system (from drive inputs to speaker) - no audio.
2) Online XML Callbook information does not populate the "Name," "QTH," and "Grid" on every instance of a callsign being selected. Information populates the blocks about 10% of the time; information needs to be manually inserted into blocks 90% of the time.
3) Callsign information is not routed to (DXLab Suite's) Pathfinder for information look-up until after a QSO has been logged (and info goes to DXKeeper logging software).
Reverted back to JTAlert Ver 2.15.0 - the most trusted version of the Ver 2.15.x series.
