Hi Ronnie,

At first glance, I don't see anything unusual in either of the two 
files. So for now, I'm assuming that the CAT connection to your 
FT-7300MK2 is working perfectly.

However, audio connections don't go through Hamlib. So if it's just a 
matter of audio problems, then the cause is likely something other than 
Hamlib.

I saw in your other posts that you are using Windows 11. Therefore, the 
following things are relevant:
1. Is the audio communication between WSJT-X and you rig allowed in 
Windows 11's security settings? At least, any "microphone" has to be 
allowed first. But it is not very likely that this blocks any outgoing 
audio from WSJT-X.

2. Please verify that the correct audio from WSJT-X goes to your radio. 
Note that WSJT-X has two audio outputs: One for the normal signals, and 
a second one where the alert sound are to be played. It is important, 
that your FT-7300MK2 is connected to the correct output channel, and 
that this signal is not muted on Windows level.
You can check this for example using Windows' old "Sound" settings dialogue:



3. Ensure that your audio connection is not blocked by third-party 
security software. I'm aware of at least one widely used security suite 
which has its own audio firewall. If you use anything like that, make 
sure that WSJT-X is not blocked there.

4. Make sure that both WSJT-X and your FT-7300MK2 are properly 
configured regarding audio in/out, (hardware) mode, etc. For example, 
with my FT-991, I have to set WSJT-X to “Data/Pkt” mode and configure 
the FT-991 to use USB audio instead of the microphone. If I set Mode to 
“USB” in WSJT-X, the FT-991 would incorrectly use the handheld 
microphone instead of the digital audio signal from WSJT-X coming in via 
USB.
