I was using DAX Audio RX1 to connect to FLDigi in a Win10 PC, SmartSDR 2.0.19. Today, the only DAX audio I see is the "RESERVED" DAX audio. It seems that FLDigi works with "DAX RESERVED RX1 AUDIO" but the manual says that I should avoid the reserved channels. Does anyone know how to get back the "non-reserved" channels? Looking at the sound window, those channels are absent. I have rebooted the PC and restarted the 6500. No change. Note: Now I see the "non-reserved" DAX audio channels in the "record" tab, rather than the playback tab, so i can't select one from the speaker icon on the task bar.
