The error says something about an invalid command "Listed" not sure where that is.
The answer is in the error message:
Syntax error on line 6 of /etc/apach2/ports.conf;
Invalid command 'Listed' (...)
This (https://i.imgur.com/Wg7ittr.png) is the error I always get when I try to open my VM in VirtualBox, and I have no idea what to do. Can anyone help?
I followed the tutorial on this site, to get my RaspberryPi NoIR-Cam running. After starting it i am retrieving the following error:
mmal: mmal_component_create_core: could not create component 'vc.ril.camera' (1)
sh: 1: /var/www/html/macros/error_hard.sh: Permission denied
mmal: mmal_vc_component_create: failed to create component 'vc.ril.camera' (1:ENOMEM)
This looks like a permission thing, but I executed
chmod u+x *.sh
just like they mentioned in the tutorial. Do you have any idea what I am doing wrong here?
Explanation: It is a permission problem, the RPi interface is trying to use the pi camera at the same time as something else, and that something else has root privileges.
I have used this interface before to stream PiCamera data into a webserver, and use three.js to render it and make it vr compatible. This RPi web interface is pretty frustrating for me. But, I have had that problem before. First, check your camera connection to the pi. To do this type raspistill -t 0 into the terminal. If it brings up a preview window, that is not the problem, if it doesn't bring up a preview window, fiddle with the connection and try again. Next, if that doesn't work, run ./RPi_Cam_Web_Interface_Installer.sh. This should bring up a crude GUI. Use your arrow keys to select number 4, or start camera. Once it starts, it should say 'started' next to it. You may get an error message at the bottom saying mmal: mmal_component_create_core: could not create component 'vc.ril.camera' (1)
sh: 1: /var/www/html/macros/error_hard.sh: Permission denied
mmal: mmal_vc_component_create: failed to create component 'vc.ril.camera' (1:ENOMEM) (or the same error you got). To fix this, close the terminal, open up a new one, and cd RPi_Web_Interface and then run again ./RPi_Web_Interface_Installer.sh select configure, enable autostart and camera. Then reboot. When the pi boots up, immediately open a terminal cd RPi_Web_Interface and ./RPi_Web_Interface_Installer.sh and check if the camera is started (you will know because the green started message will be next to the start option). If it isn't started, start it. IF you get the same error messages, I don't know what to tell you.
Had this exact error so:
ran sudo raspi-config and re-enabled the camera -problem went away
I have a Raspberry Pi that I'm trying to hook-up to walkie-talkies to announce the current time every half hour plus different status updates automatically.
I had a CRON job running mpg123 that was announcing the time over the walkies perfectly, but then when I installed the drivers for this RasClock module as specified here (https://www.modmypi.com/blog/installing-the-rasclock-raspberry-pi-real-time-clock), all audio stopped working.
speaker-test says:
speaker-test 1.0.25
Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
Playback open error: -1,Operation not permitted
and mpg123 says:
[module.c:142] error: Failed to open module jack: file not found
[module.c:142] error: Failed to open module portaudio: file not found
[pulse.c:84] error: Failed to open pulse audio output: Connection refused
[nas.c:220] error: could not open default NAS server
[module.c:142] error: Failed to open module openal: file not found
[audio.c:180] error: Unable to find a working output module in this list: alsa,oss,jack,portaudio,pulse,nas,openal
[audio.c:532] error: Failed to open audio output module
[mpg123.c:897] error: Failed to initialize output, goodbye.
Now, the machine tends to freeze up a lot, too. When I tried suggestions I found online, such as adding "LD_LIBRARY_PATH=/usr/lib/mpg123" or "export LD_LIBRARY_PATH=/usr/lib:/usr/lib/mpg123" before the command, it made no difference.
What little hair I have left thanks you in advance for helping me through this.
I had the same error message with mpg123.
Before this message, I installed all these packages: mysql-server, build-essential, libmysqlclient-dev, libapache2-mod-wsgi.
I also changed group:
# usermod -G anothergroup pi
One of these two manipulations have caused my problem.
The solution in my case ?
Go in the /etc/group file and modify the line beginning with "audio" from this...
audio:x:NN:
to that...
audio:x:NN:pi
N.B.: NN is the GID. pi is the Raspberry Pi's default username.
To achieve the same result, there is also this command :
# usermod -a -G audio pi
Log out from your session and log in again.
P.S.: Could somebody add the mpg123 tag because I spent a lot of time without finding this topic, as I have exactly the same problem with mpg123 ?
I had the same issue run this command should fix it modprobe snd_bcm2835
