Thank you

I follow the steps, installed pyaudio and ran the script. 

Recieved:

run it from the command line python usrpaudio.py
you may also need pyaudio
apt-get install python-pyaudio

That doesn't seem to have an effect, unless I'm running the py script incorrectly. ( using Thonny)

Sure. 

So return:

outputAudioDevice = /dev/null           ; Audio device /dev/null, /dev/dsp1, po$

inputAudioDevice = /dev/null            ; Only used for dongle mode

And I believe this is stock, save for the last four lines

[USRP]

server = 127.0.0.1                          ; IP address of Allstar/Asterisk

toASLPort = 32001                        ; Analog_Bridge <-- ASL

fromASLPort = 34001                    ; Analog_Bridge --> ASL

aslAudio = AUDIO_USE_GAIN     ; Audio to ASL (AUDIO_UNITY, AUDIO_U$

agcGain = -5                                  ; Gain (in db) of the AGC filter

dmrAudio = AUDIO_USE_GAIN    ; Audio from ASL (AUDIO_UNITY, AUDIO$

dmrGain = 0.6                                ; Gain factor of audio from ASL (0.0-1.0)

Trying the script now.

Lou,

If you want to help us and play a little:
- Grab the python code in this message: https://dvswitch.groups.io/g/main/message/1340?p=,,,20,0,0,0::relevance,,USRPAudio,20,2,0,19300038
- Return your Analog_Bridge.ini audio section back to stock (turn off AB local audio)
- Make sure your SignalLink is the default audio device
- Make sure your USRP ports in AB.ini are set to the defaults
- Run the python app above and it should get USRP packets from AB and turn them into audio which is output to the default audio device.
- The SL vox should take over the ptt processing.

If you hear audio come out of your radio, then transmit on a local FM radio and press the space bar on the python app (it was ment for another purpose).  If that works, I can port some simple vox code into USRPAudio.py
