I'm using an USB sound card and I test my microphone and headphone by using sox. All of them works well.
Here's my arecord-l outputs:

pi@raspberrypi:~` $ arecord -l
**** List of CAPTURE Hardware Devices ****
card 1: Camera [H264 USB Camera], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 2: Audio [USB Audio], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0

Here's my .asoundrc：

pcm.output {
type hw
card 2
}
ctl.!default {
type hw
card 2
}

When I was using barnard, the headphone was working ,but the microphone does not seem to be working. I could hear other people talking but others could not hear me.

By the way , is this project EOL?

Requested via email:

A start parameter that defines that TX should always be active.

I get the following output after connecting to the server and hitting F1, any ideas?

I am using this on a raspberry pi. When i updated (fresh install) to Raspbian(debian) stretch, Barnard started giving me trouble with the jack server: if I use jack2 it asks for d-bus (not working because in headless mode), and if I use jack1 it gives me "unknown option character l".

I still can't understand exactly where this option is used.

Thank you in advance,
Pier

First: Thank you for sharing the possibility to have a command line based mumble client!

Machine: Raspberry Pi 3B+ with Stretch
What i did so far:
Installed Mumble Server:

$ sudo apt-get install mumble-server
$ sudo dpkg-reconfigure mumble-server // with autostart --> yes, higher priority --> yes, passw...

Then i installed the required dev libs for barnard like:
$ sudo apt-get install golang libopus-dev libopenal-dev
and installed barnard with

$ export GOPATH=$HOME/go
$ go get -u layeh.com/barnard

ALL on THE SAME MACHINE (because thats what I'm after ;-) )

When i try to start barnard with
$ ./go/bin/barnard
, I'm getting an error like
x509: certificate is valid for Murmur Autogenerated Certificate v2, not localhost

My thoughts are:

1. no server certificate?
2. no client certificate?

I read about a similar problem over here layeh/gumble#4, so I think there's no server certificate, or probably just a not trusted one.

At this point I of course tried to find a way to install a certificate or to sign one myself. I just don't really know how to do that and where to find a way to do it. I tried to connect my phone to the mumble-server and the mumble client asked me, if I wanna trust the server certificate. I hit "Install" and everything worked.

So my question probably is more like:

1. How can I get that error away
2. Do I have to get a certificate (maybe from lets encrypt) and HOW?
3. How Do I sign my own certificates for Mumble, so that barnard trusts them or even asks me for trusting it.

possible i am a to big stranger of the compilation process of software written in go... but ive got a problem in compiling barnared:

gwtest@vps538:~$ mkdir -p go-apps/src
gwtest@vps538:~$ cd go-apps/src/

gwtest@vps538:~/go-apps/src/barnard$ 

can anyone offer insight to my problem here?

barnard installed, attempting to connect to a win7 murmur server.
plumble (android mumble client app) connects successfully

i've generated a certificate on the plumble android app, and transferred it to the barnard install dir on my pi.
i then ran the following command to convert the .p12 cert to a .pem:

openssl pkcs12 -in plumble-2017-04-26_22-36-48.p12 -out certificate.pem -nodes

the conversion seems to work, but when trying to connect:

go run cmd/barnard/main.go -server=192.168.1.123:64738 -username=”front_door” -insecure=true -certificate=/home/pi/.go/src/layeh.com/barnard/certificate.pem

i get the following error:

x509: cannot validate certificate for 192.168.1.123 because it doesn't contain any IP SANs
exit status 1

the murmur server log shows this:
2017-05-13 11:55:32.583 1 => <1:(-1)> New connection: 192.168.1.169:57870
2017-05-13 11:55:32.875 1 => <1:(-1)> Connection closed: The remote host closed the connection [1]

does anyone know what's going on here?? I'm so close!

thanks in advance,
Dan

Hi,

I am having issues with installing
Now as root again (sudo -i), edit /etc/systemd/system/mumble.service appending -username USERNAME_TO_REGISTER -certificate /home/mumble/mumble.pem at the end of ExecStart = /home/mumble/bin/talkiepi

Description = Mumble Client  
Requires = systemd-user-sessions.service network.target sound.target
After = multi-user.target

[Service]
User = mumble  
Group = mumble  
Type = simple  
ExecStart = /home/mumble/bin/talkiepi -username test -certificate /home/mumble/mumble.pem  -server 192.168.1.1:64738
Restart = on-abort  
RestartSec = 5

[Install]
WantedBy = multi-user.target```

Is this correct also if i use nano to edit said i don't have permissions 

Thanks for any help given

I managed to compile on raspberry pi, it does join my server
However when I press F1, it prints [11~

and does not transmit

I can receive sound, it seems to work, but I just can't speak !

Hi
I checked out the issue titled instructions and assumed Fn1 is the key to have push to talk enabled. The program crashes when I press Fn1.

Is it possible to enable audio all the time instead if push to talk?

Thanks

Everything works great but if there's an abundance of users/channels I cannot scroll the list to see them.

To be able to build Barnard with Docker.
Additionally, it could be distributed as a public Docker image to avoid installing Golang build deps.

Running on Raspberry Pi 3.
About 2h of listening to a mumble server with occational, short issues where it was playing parts of the audio too fast, then at highly reduced speed until it catches up. Each occatiob about 0.5-3 seconds.
25% cpu load idle, 50% while someone is speaking.

THEN it is silent for a longer time, then comes back full if glitches and never resyncs. Staying at about 70% cpu load.
Is it possible for there to be a memory leak piling up over time?

Requested via email:

A start parameter that defines a mumble room in which bernard shuld go right after the connect.

How can i run barnard on boot using a raspbery pi and pi os lite so no GUI. I tried rc.local but it said that it couldn't find barnard but it is installed and working

Hi,

thanks to the help earlyer (issue #1) i was no able to compile barnard on another maschine. But now i am getting erros running it. I dont know if that is because that pulse error, i want to use it with alsa only, or something else. Here are my result:

pi@treakisraspi02:~/go-apps/src/barnard$ go run cmd/barnard/main.go -server="voice.mumble-funk.de:64738"
AL lib: (WW) alc_initconfig: Failed to initialize backend "pulse"
x509: certificate is valid for Murmur Autogenerated Certificate v2, not voice.mumble-funk.de
exit status 1
pi@treakisraspi02:~/go-apps/src/barnard$ 

thanks in advance

Fantastic library. I'm trying to add a feature where it displays an indicator of who's speaking beside the username. something like layeh S

Any thoughts on how to implement this?

Hey there, just wondering if there is more documentation on how to actually use this. I wanted to use this a my test server

go get outside a modual is no longer suported.
It should be: go install layeh.com/barnard@latest

Hi, so after installing gumble i get this error installing barnard

go get -u github.com/layeh/barnard/cmd/barnard
# github.com/timshannon/go-openal/openal

                  ^
compilation terminated.

what should i do?

PS, installing gumble and termbox go does not give any output, it simply takes some time then let me put the next command, no message displayed, is it ok?

I wanted to congratulate the wonderful project

I wanted to know if it is possible to implement a LED that lights up when the Stram is received.

Thank you

You may want to add this to the readme. Took me a while to figure this out, so as to save anyone else the effort, here is how to convert your Mumble GUI's generated p12 cert to the pem format for usage with barnyard:

openssl pkcs12 -in /path/to/your/mumble-cert.p12 -out /path/to/your/mumble-cert-barnard.pem -nodes

Then you can use a commmand to load up like:

barnard -certificate="~/certs/barnard.pem" -server=server.com:64738 -username=YourName

To create a new pem from zero:

cd /path/to/where/you/want/cert/to/live
openssl genrsa 2048 > private.pem
openssl req -x509 -days 9000 -new -key private.pem -out public.pem
openssl pkcs12 -export -in public.pem -inkey private.pem -out mycert.pfx
openssl pkcs12 -in mycert.pfx -out barnard.pem -nodes

And of course if you register this user, you can launch it with only the server and cert flags, as the server will know the user now (hence the point of registering).

Hope this helps folks out!

Hi,
Just a quick note to say that I had my terminal window on Ubuntu 10.04 set much wider than normal when I first tested Barnard (running over ssh on a Raspberry Pi running Raspbian Jessie) and most of the screen that would normally be clear was covered in random Unicode characters. The channels were legible as was the welcome message. When I resized the terminal to make it smaller, the screen quickly sorted itself out and I now see something almost identical to that in your readme. Strangely, if I make the screen wider again, it remains OK.

Actually, having now exited and restarted this seems to happen even if my screen is not abnormally wide. Making the screen wider also seems to sort out the rendering.

barnard doesn't compile properly on my end:

I installed Go on my Ubuntu machine via

sudo apt install golang

and then ran

$ go get -u layeh.com/barnard

However, next thing I get is this compilation error:

> # github.com/dchote/go-openal/openal

         ^~~~~~~~~

Am I doing something wrong? Thank you!

Hi,
When using barnard, i a press F1 to stop stream and then press again to start stream there is no sound.startSource() is working but if i call stopSource() voice wont come back.What is the problem ?
We are using Raspberry Pi 3 and Rasbian image.
Regards..

I get this message when trying to install. I know nothing about go other than hello world which confused me to the extent that I stopped investing time in picking up go and switched to android development as my primary time sink ¯_(ツ)_/¯

$ go get -u github.com/layeh/barnard/cmd/barnard
# github.com/timshannon/go-openal/openal

Thanks for any tips.

barnard -server "<our server>:64738" -username "Cloud" -password "<our password>" -certificate key.pem

With the missing info properly replaced in that, i run it and get a plain EOF with nothing else.

Can you add the ability to auto-attempt to reconnect to server after n seconds, if specified from the commnad line.

ie.

barnard -reconnect 120 ...

And if the client become disconnected from the server then it will automatically try and reconnect every 120 seconds.

I don't know whether this is related, but I just upgraded to Debian stitch. An issue was introduced that I'm trying to sort out, and I attempted to upgrade barnard via the command in the readme. I don't think barnard is the problem in that chain, I was updating it in an attempt to narrow down the problem.

As near as I can tell, my install from April 12th is working as it was before the system update to stitch. I have tried updating the existing install, as well as a fresh install into a new directory (and yes, I did point the go path at the new install directory). The new install attempt just gets me the src and pkg directories and no bin directory.

I think there sould be introductions on how to install this application.

Would be nice to place barnard.yaml in ${XDG_CONFIG_HOME}/barnard/config.yaml or ${XDG_CONFIG_HOME}/barnard.yaml if defined.

While receiving audio, barnard's RAM usage is growing about 1MB every 10 seconds or so for me. Doesn't seem to get garbage collected, will just grow until the system kills barnard. I did update via 'go get -u github.com/layeh/barnard/cmd/barnard' before reporting this.

I have deep nested channel structure with long channel names on my server, can you add scroll feature to treeview widget?

Is this just for text chatting or is it able to also send voice (from local mic or "what you hear")

I have been trying to work out what controls are active in the UI.
*The Tab key shifts the focus from the message box to the channel selector and back again
*Fn10 acts as Quit - It would be helpful to new users if this fact could be added to the Welcome Text.
*PgUp and PgDown scroll messages as do Home and End.
*Ctrl + L seems to clear all messages.
*Fn1 looks like it may work as Press to Speak - switching the word "Idle" for "TX" whilst it is active - is that a fair summary ? If so, this is an issue because on Ubuntu at least F1 seems to be mapped to a Help page for the Terminal. Can anyone suggest a workaround for this?

The main thing that I haven't found is how to configure the sound. Please advise.

I've complied Barnard using Golang 1.6.2 on a Raspberry Pi Zero ARM6 @ 1GHz.
All works well. Audio is received perfectly with minimal latency, but transmitting audio is delayed several seconds.
Running Top I see CPU usage is above 90% when running Barnard in transmit mode. When not transmitting the CPU is around 4%. When receiving only, CPU is around 25%.
I assume the high CPU when transmitting is due to audio compression and encryption which is therefore causing the long delay.
I am willing to sacrifice compression and/or encryption to get the CPU usage down.
Is this doable? And will this solve my problem?

Hi, so i have a raspberry 2 but i'm not able to install it. I want to have this so i can autostart the client at boot and autoconnect it to my local raspberry server (another rasp). Could you guys please give me all the links to install it? Thanks

Hi, great project! Installed it today on a raspberry pi 2 and connected a Logitech c920 webcam/microphone to it. I am able to record using the webcam microphone with "arecord" however barnard will not transmit any sound. F1 does set me in tx mode but there is no sound transmitted. I have ensured that my microphone is the default capture device. Any suggestion will be greatly appreciated.

P.S- I am working on implementing the "always on" capability and will submit a pull request soon ;)

OK, im quite certain that thats a bug:

i had barnard running, still dont know how to switch channels, and then ive reconnected my Internet (pppoe reconnect of router) and that resulted in a crash of barnard with an unusable terminal. please fix that. In addition ill send a screenshot.
