usbradio - no RX audio

[Mason10198]

Using a DMK URIxB connected to a Pi4 running ASL2.0.0b6, SimpleUSB works perfectly for both RX and TX. With the same connections, USBradio does not get RX audio.

asl-menu -> radio-tune-menu -> Set Rx Voice Level (using display) ---- audio meter does not budge asl-menu -> radio-tune-menu -> Toggle echo mode ---- does not echo anything

/var/log/asterisk/messages shows the following when USBradio is enabled:

I do not have a DMK URIxB to test with, but have you tried setting carrierfrom=dsp in usbradio.conf and seeing if the issue persists?
