Change DAX RESERVED AUDIO RX 1 to DAX AUDIO RX 1 in wsjt.

I don't think "DAX RESERVED AUDIO RX 1" is the correct sound Device, Here are the correct settings for Slice 1 "DAX AUDIO RX 1".
I think the "RESERVED" device's are used internal to the computer.

Also, be aware there is a known issue where after some period of time for some people DAX will become corrupted. The only known solution is to restart DAX which means restarting WSJT-X as well.
Flex knows about the issue and is working on it.
I have the issue when using DAX 1. If I switch to DAX 3 I do not get corruption.
Just FYI0 -
In many cases it also works to simply cycle the DAX RX Channel off and on in the DAX COntrol Panel. This resets the DAX Buffer. and It usually does not require restarting WSJT-X. Other cases require a restart of DAX.
And Yes, NEVER use the RESERVED audio drivers. Those are reserved as the "Radio End" of the virtual audio cable.0 -
Thanks for all the quick responses.....while I was waiting...I uninstalled DAX and reinstalled and all is working now.....apparently there was an issue with DAX talking to WSJT....

Well it worked fine...stopped and I had to restart DAX....worked then stopped again......I tried RX3....but that didn't work either.....restarted...didn't work......went back to RX1 and nothing....I have tried every DAX Channel...nothing...then suddenly started working on DAX 40

Constantly having to restart DAX......works a few minutes...then stops...useless this way....

It drives me crazy as well. I have to play with DAX everytime I change profiles. Been thinking about going back to 2.4.9 as many others have. Other things to check would be the PC time and a reboot of everything including the router. Start fresh.

Locate sound panel and check "listen to this device" to hear the data stream from DAX. If it becomes scratchy sounding etc it's time to restart DAX. DAX can become corrupt if run for long periods of time or if the computer fails to provide prompt service time for the application.0 -
Thanks.....I have rebooted a lot.....but not the router....
It quit again...then I selected a different channel....started working......about a minute later it stopped....

Are you sure your time is exact? sounds like you may be off a few seconds0
-
Well..it doesn't run long enough to be able to use WSJTx.....

Try setting your computer time with your phone time as close as possible, and try that.0

We have seen this procedure cure WSJTx issues. Not sure if it will solve this one.
1) Close WSJT-X, SmartSDR, DAX, CAT, etc.
2) In Windows, find your "C: > Users > username >Local > AppData >WSJT-X" file folder.
3) Rename the WSJT-X folder to "WSJT-X-Old"
4) Reboot the computer
5) Restart SmartSDR and CAT.
6) Restart WSJT-X and it will rebuild the AppData folder.
7) You will need to recreate your configuration settings.
8) Test it.
9) if it now works, go to the WSJT-X-Old and copy your wsjtx.logand wsjtx_log.adi files to the new WSJT-X folder. If it asks if you want tooverwrite the existing (new) ones, say OK.
This process may work to eliminate a corrupted configurationfile in the WSJT-X folder.

Here is a link to a discussion on the WSJT-X board regarding latency issues with WSJT-X, Windows and DAX. Bottomline.... Complex interaction between WSJT-X, Windows and DAX drivers and programs. Note in this posting Flex/ Tim Ellison was supportive but there was no magic.

I quit trying to get DAX and WSJT to play together.
Would finally get things sorted, then stopped working the next hour or the next day.
Secondly, my (very) remote site has such poor up-link bandwidth, DAX was just too bandwidth heavy.
The fix here has been VBAudio. It has worked flawlessly on the remote both 6300 and 6500 for two years. Little bandwidth (compared to DAX) and reliable once set up.
Must be set up in audio / recording and playback. WSJT settings / audio input / output.
Very reliable on low bandwidth connection remote. Comes up "everyday".

What worked for me when I had similar problems was just to make a new wsjt-x configuration file. Somehow the configuration file I was using became corrupt. Might want to try this before trying the above.

Change to dax 3 and see if same result. My dax 3 is good, dax 1 continuously corrupts.0
