I had this problem with a misconfigured deemphasis setting in simpleusb.conf.  Typically, you uncomment the following line only if you are tapping audio from the radio’s discriminator output.

;deemphasis=yes         ; enable de-emphasis (input “to the node’s usb dongle” from “radio’s” discriminator)

Your audio levels could also be to low or too high.

Hello,

DTMF tones not being received to control node all else working.

Would appreciate it if someone can head me in the right direction.

Thanks,
