All I did is to snap it. But since Ubuntu Core does not ship with ALSA, I also included some ALSA utilities such as speaker-test and aplay. INTERFACES THAT NEED CONNECTING Please keep in mind that Ubuntu Core installs snaps in strict confinement mode by default. This means you need to connect interfaces. Here's what I am now seeing on my RaspPI: skidooman@ubuntu:~$ sudo snap connections mpg123-core Interface Plug Slot Notes alsa mpg123-core:alsa :alsa manual network mpg123-core:network :network - network-bind mpg123-core:network-bind :network-bind - The network and network-bind interfaces should be connected automatically. However, alsa and home will need to be connected. In order to do so, on your Ubuntu Core, at command line, type sudo snap connect mpg123-core:alsa JUKEBOX The Jukebox capability is enabling mpg123-core to be able to launch music "at a distance". For example, say that you have a Ubuntu Core on a RaspPI running mpg123-core snap. In order to "launch" Jukebox, write the following into the browser of your choice: http://:5000/jukebox?command=start IF you have mp3 files in /var/snap/mpg123-core/current/, then Jukebox will select one of them and play it on the output outlet of your choice. Typing this url will stop the music: http://:5000/jukebox?command=stop There is no option for multiple tunes, specific tunes, etc. Eventually maybe I can implement it, or an eventual collaborator can do it. USAGE AND OUTPUT SELECTION For the speaker-test and aplay tools I worked a lot on this. First try this: sudo mpg123-core.speaker-test -Dhw:Headphones (For where that -D flags comes from, keep on reading - it MAY be different for you!) Then, you can try to play something from aplay as well (it only takes WAV files, and then there are sometimes limitations on the type of WAV files it can play - sampling, etc - so beware) sudo mpg123-core.aplay -Dhw:Headphones For mpg123 proper The command line looks different. Don't use -D, use -o sudo mpg123-core.mpg123 -o alsa:hw:Headphones At this point, I only used ALSA, and it works. For Jukebox By default, the flag being passed to ALSA is hw:Headphones, which is valid on my system. If you need to change, you need to write a valid json file named /var/snap/mpg123-core/current/output.json For example: {"output":"hw:Headphones"} How to determine the string that fits your system Now, if you do not know how to get that string ('hw:Headphones'), I struggled with this also, so here is the procedure I figured out: skidooman@ubuntu:~$ sudo mpg123-core.aplay -L null Discard all samples (playback) or generate zero samples (capture) default hw:CARD=b1,DEV=0 bcm2835 HDMI 1, bcm2835 HDMI 1 Direct hardware device without any conversions hw:CARD=Headphones,DEV=0 bcm2835 Headphones, bcm2835 Headphones Direct hardware device without any conversions As you can see, hw:Headphones maps to hw:CARD=Headphones. If I wanted to use HDMI instead, I would ASSUME: hw:b1 would work - but since my lab's monitor has no sound, I cannot test it. UBUNTU NOT CORE (or another Linux etc) I worked on this snap for Ubuntu Core only. If you do not know what Ubuntu Core is, it is our version of Embedded Linux. Obviously, installing on Ubuntu Core supposes that there is a sound card on your board and it is working at a kernel level. --- That is all I can think about. Hopefully it helps someone else in the community. Happy Ubuntu-ing!
