DAX Issues Returned After 3.4.21 Upgrade

Just curious if I am the lone ranger on this issue? Long story, but after several years of no DAX issues (or a while), I suddenly started getting distorted RX audio (first noticed on no decodes on WSJT-X). 6600. Initial fix was to uninstall-reinstall SmartSDR (including clean DAX, removal at install prompt). Would work a few days, then bomb out again. A second PC in the shack, would often continue to work, but eventually a re-install there needed as well. Several cycles of this (both PC's) over several weeks. Work a few days, then trouble again. Terrible. Even did ultimate clean installs with registry cleaning as well. Then, troulbe again and again, about 4 cycles. Today, decided for a factory reset (by procedure, power removal & timing, white light, etc.). Working right now, but time will tell. Any feedback? Most strange and annoying, with Murphy's Law of every time there's rare DX!!

    Will do!! Thanks Mike. Fingers crossed. By the way, the other PC was not re-installed (SDR) this last time, and the factory hard radio reset did NOT fix it. SO, it seems PC / DAX related probably not "radio" (box) related, but who knows. Sometimes it fails on both PCs at the same time, sometimes one will continue to work for a while before failing. Both Win10 boxes, both on local network LAN. No issues whatsoever until .21 :(
