Hello,
I just installed the client on a brand-new PI-4 and I always get the same error.
Here the complete log of one observation:

The image installed is “2019-09-11-Raspbian-SatNOGS-lite.img” with all latest updates (29/02/2020).

Can anybody help me. Thanks!

Hej,

did you use driver=rtlsdr in the SATNOGS_SOAPY_RX_DEVICE setting (assuming you want to use an rtl-sdr) ?
After upgrading from 1.0 to the newest 1.1 satnogs-client i used the old rtlsdr string without the driver= and i also got some errors about samplerate not supported as it tried by default to open my soundcard at 2MS/s. Also setting gain failed. Fixing the device string made it correctly open my SDR device.

Maybe in your case it is also trying to fallback to the audio device because of an error in the device string.
