vban_emitter error in raspbian

[QuantumFluxCapacitor]

Hi, I am trying to setup a vban emitter to vban receptor stream, and the receptor works fine but when I start vban emitter i get the following error (no matter which options i use):

pi@raspberrypi:~/Documents/vban-master $ vban_emitter --ipaddress=10.19.71.2 --port=4464 --streamname=x vban_emitter version 2.1.0

the ./configure part I used --enable-alsa --disable-pulseaudio --disable-jack before compiling.

This is on raspbian buster but this problem also popped up in stretch and on both an Rpi 3B+ and an Rpi 4.

I hope you can help me on this one. Thanks in advance!

Hi, that arecord reports the same error than vban_emitter is a good hint that the ALSA "default" input device is not properly working / configured. I would run $ arecord -L to know what are the input devices (aplay gives the output ones), and try to use one of them explicitely, eg: pi@raspberrypi:~/Documents/vban-master $ vban_emitter --ipaddress=10.19.71.2 --port=4464 --streamname=x --device="hw:CARD=ALSA,DEV=0"

I got the app to run. It worked fine, even with kodi (After I configured and compiled vban_emitter for pulseaudio, not alsa). In kodi when one chooses the dummy output, the audio is streamed nicely to the remote site.

But now I get the same fatal error when I start vban_emitter as a systemd service. It exists immediately, or restarts indefinitely. To recap: From a shell i can start vban_emitter manually, which works fine. When started as a service, it gives the same error I reported initially.

Please close this issue. I will rephrase the issue with vban as a service in a new issue report.
