ideas for resolving DAX and Icom audio conflicts ?

I installed Icom drivers on my Windows 10 PC and find that despite a seemingly good install I cannot use digital mode software with the Icom codec IF  DAX is present on the PC ?  Dax works fine with the Flex but when using an Icom with the digital mode software audio paths set for the Icom codecs, no audio is visible in the waterfalls (Flidigi, Multipsk, etc ) ,  IF I uninstall DAX, audio from the Icom , audio is visible on digital mode software waterfalls as one would normally expect ?

I would appreciate any ideas on resolving this (other than not buying Icoms )

I have used the 6500 exclusively for digital since I got it.  I have an Icom 9100 that I use for 2 meters and HF backup that I put it on WSJT-x yesterday with no issues.

So in your case shutting off the DAX still wont work?

I assume you are using the mic/speaker USB audio Codecs?

I have a local friend running a 7410 on WSJT-X on a PC with DAX and he has no issues either.

Yes, I am using the mic/speaker audio codecs.  IF I look real closely i can see a tiny trace of signal from the Icom when DAX is present on the PC and lots of signal when DAX is absent. Yes, DAX is OFF.

If you crank up the level on the USB codecs does it help?  Have you tried anything besides FLDIGI?

I tried sveral other digital mode software.  I am going to load on to a PC that has never had SmartSDR and use the Icom and see if the issue goes away.  I

Do you see activity on the windows bar graph in the sound control panel?

Keep in mind it might be backwards to what you think. Its actually the microphone and not the speaker you have shown.  So make sure you click your recording tab and check the USB Codec for the mic.
