DarkIce is a live audio streamer. It records audio from an audio interface (e.g. sound card), encodes it and sends it to a streaming server. This is the official development repository of Darkice.

I don't understand what the error message is, is it the connector to the sound 
device
or to the server?

Having the same problem, has also occurred just after losing network 
connectvity and I snuck a reboot in during the down time. I tried changing 
[icecast2-0] to [icecast1-0] and have tried using [icecast-0] and a few other 
derivatives. Still receive the error after running darkice as root:

Checking the source code.. I think it could happen like this if some other 
application is using /dev/dsp. Maybe some zombie process around? Try to check 
who has /dev/dsp open with 'lsof'.
If there is another dis-functional darkice, kill it with 'killall -9 darkice' 
Some more 'human-friendly' error message might indeed be helpful.

Here is a little patch agaist HEAD, it add a more verbose reporting :

Hey folks.  A heads up for you.  OSS has been thrown aside in newer Linux 
distros in favor of Pulse Audio.  In addition, OSS has undergone important 
revisions recently.  I spent the better part of an afternoon yesterday fighting 
1140: Can't Open Connector and the first thing I noticed was a total lack of 
/dev/dsp on my system.  I'm going to bet you're going to find the same thing.  
No /dev/dsp means no DarkIce unless you can get it to latch onto the correct 
sound device on your system.  I did try getting it up and running on Pulse but 
with no success so I had to manually compile OSS on my server.  Does DarkIce 
play nice with Pulse Audio?  If so, what device should DarkIce be looking for??

hi,

alsa is the default linux driver. To try it, this should work (if darkice is 
compiled with alsa support as it should) :

[input]
device          = hw:0,0

Select and adjust input with alsamixer (in a terminal )

To test if hw:0,0 is the correct device , use this command :
arecord -f cd --device=hw:0,0 test.wav
This record the input to test.wav 

good luck
Laurent

You can also try with:
device = default

This worked for me anyhow.

Hi, I have this problem. I have 4 USB sound card.
When I use 
device          = hw:0,0
i hear all 4 sound card
When I use

Okay, so my errors have disappeared now, after switching to "default" as the 
device, but how do I know if it's working? It just says "0 bytes transfered to 
the encoders":

Hi, it looks like I'm getting this same problem. I installed from the FreeBSD 9 
ports tree, and it built fine, however when I try to start it, I get the error:

Using config file: /usr/local/etc/darkice.cfg
Using OSS DSP input device: /dev/dsp
Using POSIX real-time scheduling, priority 3
DarkIce: DarkIce.cpp:1201: can't open connector [0]

I have OSS and /dev/dsp, but darkice doesn't seem to be able to connect.

I also tried installing from the repository here, but the configure script 
couldn't find any of my audio libraries.

Config file is the default, with just names and passwords changed.

Hey I'm running ubuntu studio 16.04 same issue: DarkIce: DarkIce.cpp:1201: can't open connector [0]

I tried with jack, jack_auto and hw:1,0 (my usb soundcard) Setting to default avoid the error but stream remains silent.

hexagon5un commented 6 years ago

Had this error, came here, tweaked around the sound card in ALSA (hw:0,0) and updated the config and then it worked.

Hubcapp commented 4 years ago

try running darkice not as root or with sudo. :D

NightPurrer commented 3 months ago

I have the same problem. DarkIce: DarkIce.cpp:1273: can't open connector [0] I tried to run as root, as normal user, tried device=default or device=hw:0,0 but no results. Finally i written the sound cart name but the same thing again. Cart is also used by another app to transmit audio for web. It's FM DX server. It can cause the problem? Here's my config: [general] duration=0 bufferSecs=5 # size of internal slip buffer, in seconds reconnect=yes realtime=yes rtprio=3 [input] device=hw:U192k sampleRate=44100 bitsPerSample=16 channel=2 [icecast2-0] bitrateMode=abr format=vorbis bitrate=192 server=dmsrv.pl port=8001 password=mypassword mountPoint=krk name=KRK description=Restream z Krakowskiego tunera umozliwiajacy odlsuch url=http://dmsrv.pl:8001 genre=Alternative public=yes

maxboone commented 2 days ago

In my case I was running PulseAudio in the userspace and darkice as superuser in a systemd init. Moving darkice to run as a user service (or adding the correct XDG_RUNTIME_DIR=/run/user/1000) fixed the issues.
