No RX Audio on 20M USB

I am using the latest version of SmartSDR Mac. This morning I came into the shack and my Flex 6700 was set to 40M LSB. Everything worked fine. I changed bands to 20M USB and there is no RX audio even though the s-meter bar graph and Panadaptor show the presence of signals. If I change modes from USB to CW or LSB or any other mode, I get RX audio on 20M. Just for grins I checked and there is RX audio on all other bands.

I have restarted SmartSDR, restarted the 6700, and restarted the computer. Nothing solves the problem. Does anyone have any thoughts?

    Hi Ken, I would do a factory reset. Export your profiles first, then follow the instructions in the SmsrtSDR manual for doing the reset.

    If that does not fix the problem, submit a helpdesk ticket.

    Thanks Len, the factory reset worked. I am grateful to you for providing the end to a very bizarre experience.
