When I click on Direct I/Q Output to VAC  I get an Audio Subsustem invalid device, -9988 port audio error, invalid stream pointer error. Any thoughts on how to get rid of that? Trying to get CW Skimmer working. Running KE9NS PSDR v2.8.0.40 and VAC 4.12.0.4974.

    Weirdly if I uncheck Calibrate IQ I can check Output to VAC and CW Skimmer will start to decode.

    Was able finally fix this. I loaded the newer version of PSDR from KE9NS then created a new PSDR DB. When that did not work I finally looked at the manual and made the buffer size and sampling rate of PSDR the same as the Flexradio firewire app. All issues solved and everything is working as expected.
