My setup is a Raspberry Pi 3, URIx (no eprom) and a Kenwood TK-820. I'm getting good audio out when I use iaxrpt, the IDs and times transmit fine, but inbound rf signals to the repeater can't be heard and don't trigger beeps, etc. When manually open the COS, I can hear the squelch noise and the inbound audio. Here are my settings.

Any advice on what I might be doing wrong?

Card is: 0

Name is: usb

Rx Level: 500

Rx no-delay: 0

Rx audio-delay: 0

Tx A Level: 500

Tx B Level: 500

preemphasis: no

deemphasis: no

plfilter: yes

rxboost: yes

PTT: Active LOW

PTT status: Un-Keyed

CTCSS (input): CM108/CM119 Active LOW

COS (input): CM108/CM119 Active HIGH

COS (test): Un-Keyed

COS (composite): Un-Keyed

Thanks very much for any wisdom you can share!
