Lost the DAX option for "Channel 1 RX" JT65 no longer controllable as before

I can choose DAX CH 1 TX in computer settings but not RX..for other then RESERVED channels. Have reinstalled DAX but no longer able to control JT65 xmit with vox.
Anyone had similiar issue. Windows 7.

Follow the instructions for a complete reinstall, making sure that all software is truely removed before reinstalling. I had problems with interfacing to my logging program that I could not solve. In my case, Windows was hiding some deleted ports. Fixed the port problem, reinstalled, and all was well.

Not sure what windows can do to DAX; but, I suspect that Windows has caused your problem.

Look at task manager and see if you can see the DAX channel there. Not sure if windows can hide a deleted DAX channel.

More info.. Tried a win 7 laptop to control with fresh instance of SDR 1.5.1.  Channel 1 RX still elusive. Will need to call support to see what I am doing wrong.

more.. Rebooted the laptop and found the rx1....All then worked well there. Went back to the offending Desktop machine and observed the following: In channel 1 the DAX control Panel  showed continuous activity on the TX audio side while in receive or xmit, no matter what channels were set. I went to DAX channel 2 and I was able to then show xmit activity only when JT65 went to xmit and have the radio key via vox. as expected. I suspect a corruption in DAX channel 1 only it appears.
