This one could drive me crazy. Recently, I’ve had a what turns out to be a common Windows 10/1511 to 1607 update failure and thus a couple of times to roll back to 1511 using a system image backup. The thing afterward both times is that my DSD, which is connected via USB to a JCAT card (desktop), via a LANRover and TotalDac USB cable, has not been seen by Windows Sound or in Device Mgr afterward. If I move the cable to a motherboard port, the DSD is then seen, but even then it will play just a second then stop. The first time this happened, a week ago, I eventually got the DSD recognized by replugging everything; moving the USB cable back and forth a few times between JCAT and mobo port; installing the USB driver when it was in the mobo port; reinstalling Torreys; and then reconnecting to the JCAT, with a couple of reboots tossed in. Whatever magic was involved there, the voodoo is not working this time. Btw, this same thing happened - problem and solution - a couple of years ago running Win 8.1 repairs and a different motherboard.
I’m assuming this involves something in the relation between the PS Audio USB driver, Windows OS and possibly Torreys, but I can’t figure it. Is there something in the registry to look at? Other ideas? Thanks,
