I seem to have a problem tuning the USB radio interface. Here'e what I get in the CLI. *CLI> radio tune Active radio interface is [usb] Output A is currently set to composite. Output B is currently set to voice. Tx Voice Level currently set to 500 Tx Tone Level currently set to 200 Rx Squelch currently set to 500 Device String is 3-2 Usage: radio tune <function> rxnoise rxvoice rxtone rxsquelch [newsetting] txvoice [newsetting] txtone [newsetting] auxvoice [newsetting] save (settings to tuning file) load (tuning settings from EEPROM) All [newsetting]'s are values 0-999 *CLI> radio tune rxnoise tune rxnoise maxtries=12, target=23000, tolerance=2000 tries=0, setting=2, meas=1 tries=1, setting=16, meas=1 tries=2, setting=16, meas=1 tries=3, setting=16, meas=1 tries=4, setting=16, meas=1 tries=5, setting=16, meas=1 tries=6, setting=16, meas=1 tries=7, setting=16, meas=1 tries=8, setting=16, meas=1 tries=9, setting=16, meas=1 tries=10, setting=16, meas=1 tries=11, setting=16, meas=1 DONE tries=12, setting=1000, meas=1 ERROR: RX INPUT ADJUST FAILED. *CLI> I know I have audio going into the device. When I made the modifications to the usb device, I decided not to remove the audio output jack so that I may use it for testing purposes. So I plugged some speakers in, went into alsamixer, un-muted the microphone, turned it up a little, and I had sound from the radio without any problems. So why can't asterisk hear the sound when tuning? Have I forgotten to do something else before trying this? Jeff
