Is it possible to get audio output to the headphone jack when using digital modes?

JTDX on the Mac is quite buggy and often will stop sending audio out to the USB
port. When this happens, there is no indication that the QMX is not sending audio
out anymore, even though the radio shows full power output. I used a second radio to?
verify that this was happening to me on FT8. Oh, I found that on JTDX, if I switched
the audio back to the internal MAC speakers and then back to the QMX, audio output
to the radio is restored.?

Any input here would be great appreciated.

Corey,? please check Operation manual section "Operating QMX on digital modes" subsection "Transmit status indication during QMX digital transmissions". I think it's what you are looking for.

Ludwig,

That's it! I didn't realize that the transmit indicator actually had 3 separate conditions.

Thank you and 73s

Corey, what Mac are you using? I know WSJTx on some old Macs have similar issues. When I was using WSJTx on my 2010 Mac mini with IC705, the audio stream sometimes would be routed to the internal speaker. The workaround is surprisingly simple - just change the sample rate of the radio's virtual sound card from 48kHz to 44.1 kHz. It can be done in "Audio MIDI Setup". Don't know if this is relevant though.
