Thanks for the back and forth with ideas. I'll be around

In case it was not clear, USRPaudio is a simple USRP client for Analog_Bridge. It is used in another application but we think it can be adapted to your application.
More tomorrow.

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

it looks like the SL is not the default.
Create a asound.conf in /etc

Put below in it.
defaults.pcm.card 1
defaults.ctl.card 1

- 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

Greetings,

I'm setting up an allstar node to bridge my DMR talkgroup for my local simplex group using a RaspPi.

It appears I got just about everything working and connected with my node. I can send commands and even a 1khz test tone into the talkgroup, which I hear on the DMR radios. So that bit is working; yet the purpose was to have the allstar/RaspPI key one of my radios and go out on analog 2m. 

My radio is a FT857D and the interface is a SignalinkUSB. I am able to get the Signalink to PPT via VOX if I play audio on the RaspberryPi, but can't seem to bring audio in from the DMR talkgroup to PPT the Signallink. 

I suspect the issue is specifying the audio I/O in Analog_Bridge.ini. 

Below is an lsusb output as well as the Audio Device section of Analog_Bridge

https://pastebin.com/HVK7uiRU

I'm a little turned around by this, as I am not sure how to specify the audio IO source; 1. capture the DMR audio and pipe to USB/PCM audio interface into the SignalinkUSB.

I know the comment block says "not normally needed in gateway service" ...so am I on the right track or should I be using chan_usbradio or chan_simpleusb? 

I've been trying different configurations and modules, but not having any luck.

Any ideas how I might get this done? 

Thanks in advance.

Re: Allstar & DMR | piping audio from talkgroup into USB soundcard

I'm away from the desk right now so I cant look at the config, but iirc I reset the 

Basically what I did was set the USB audio codec in pi config to default, then played a song on YouTube. That audio triggered the signalink which PTT on VOX. I also installed pulseAudio, although I am not sure if it played a role.

When the SignalLink keyed, it pushed the audio from YouTube to my radio (857) 

My thinking was if i could get it to parrot or play the talk group audio, the default output would do the trick, at least one way. 

I didnt use any command iirc. 

I may have set the audio in and out in mmdvm ini to ttyusb but I think I reset to /dev/null prior to the "YouTube test"

I'll be back at the desk in a few minutes.
