Streaming Errors with VLC on the Raspberry Pi

I’ve had tons of problems setting up my Raspberry Pi (specifically the first edition) for playing radio in sync over udp or rtp. I’ve managed to find a solution!

I would get errors such as:

@4000000056b8e5e40747ea1c [01ab9840] core audio output error: module not functional
@4000000056b8e5e40748289c [b5d19f50] core decoder error: failed to create audio output
@4000000056b8e5ed36fb571c [b4e001f8] http access: Raw-audio server found, mp3 demuxer selected
@4000000056b8e5ee04fb0c1c ALSA lib pcm_hw.c:1667:(_snd_pcm_hw_open) Invalid value for card
@4000000056b8e5ee0517276c [01ab9840] alsa audio output error: cannot open ALSA device "default": No such file or directory
@4000000056b8e5ee05a916cc [01ab9840] core audio output error: Audio output failed
@4000000056b8e5ee05cf3c6c [01ab9840] core audio output error: The audio device "default" could not be used:
@4000000056b8e5ee05cf8a8c No such file or directory.
@4000000056b8e5ee05cf9a2c [01ab9840] core audio output error: module not functional
@4000000056b8e5ee05cfb584 [b62c78c8] core decoder error: failed to create audio output

In the end, the parts that fixed it were running the command as a different user (alsa has permission issues), along with specifying the device:


runuser -l pi -c 'vlc -I http --http-port 8080 --http-password vlcremote --aout alsa --alsa-audio-device=plughw:0,0 /home/pi/vlcplaylist.xspf'
