Raspberry Pi Zero W SunVox and Linux Console Only (Without Xorg)

Post by danzigism » Wed Sep 19, 2018 8:56 pm

Hey there guys! To satisfy my curiosity I took on the project of getting SunVox to work on a Raspberry Pi Zero W without needing Xorg at all. Since SunVox uses libSDL, in theory it should work in the console without the need of a desktop environment. By eliminating Xorg out of the picture, you can save just a little more of those precious resources on your Pi. Well the good news is, it works great! Albeit, a bit of a lengthy process. The instructions should work for anything running Raspbian Lite.

I made a little video on how to do this along with a link to some written instructions for those that might be interested.

It's also a great tutorial for those that might need to figure out how to use JACK without using Qjackctl and is helpful to understand how a2jmidid and jack_connect play an important role in the whole process.

Hope you all have a wonderful day!

This is great work, sir!

But I'm absolutely newbie in linux. I loose two days trying follow your instructions. Today I have successfully starting sunvox. But jackd doesn't see any soundcard (including onboard one) but "arecord -l" does.

I need help! Please! Any way - by SSH, by skype ...

Hey there pepelnyy! Sorry for the delay in getting back to you. If JACK isn't seeing your soundcard, it's possible that the incorrect device parameters are specified in your ~/.jackdrc file. Specifically the attribute "-dhw:2,0". It might be "-dwh:1,0" in your case. But you definitely need to find the correct card and device numbers.

Could you possibly paste your ~/.jackdrc file as well as the output from arecord -l ?

Dear danzigism!
The problem is with dbus. It seems like no dbus is in my system but dbus-1 is. I really don't understand what it means and what I have to do with it.
Thank yoy for your attention!

Ahh ok, that is perfectly fine. You basically need to make sure you edit the /usr/share/dbus-1/system.conf file and create an empty space after any of the ending </policy> tags.

You're gonna create a brand new dbus policy that looks like this below. Ensure that you're using the "pi" user, or change it depending on your system.

Code: Select all

<policy user="pi">
<allow own="org.freedesktop.ReserveDevice1.Audio0"/>
<allow own="org.freedesktop.ReserveDevice1.Audio1"/>
<allow own="org.freedesktop.ReserveDevice1.Audio2"/>
</policy> 
You'll also need to make sure you edit the ~/.bash_profile file located in your home directory that has this line in it:

Code: Select all

export DBUS_SESSION_BUS_ADDRESS=unix:path=/run/dbus/system_bus_socket
Let me know if that works for ya!

Yes! I thought about something like this, but didn't know exactly what to do. Thank you very much!
Now I'm in plane, flying from Sakhalin to Moscow, but at friday evening I will try to do it and will write here about results.
One more time thank you!

Dear danzigizm!
Sorry for delay, it was really hard days!
Today I took brand new tf-card, flashed it by raspbian-lite and went through your instruction step by step.
I think you could make some changes in it, in some commads it is necessary to add "sudo".
About my progress - now I just couldn't check the MIDI-connection because I don't have my MIDI keyboard with me right now.
Sunvox starts and plays trough my soundblaster. But one thing - when I put audio by Jack I can't change buffer length and can't choose audio device, only "Auto" is suggested. In case of ALSA I have choice of all my audio devices and can change buffer (and latency) and can to choose "JACK" as MIDI input. Will it work?
Thank you!

p.s.: here is output in SSh console if we run Sunvox trough SSH. May be you will see there something that I don't :)

Hurray!!!
Yesterday evening I had tried to connect MIDI keyboard. And it works. I hadn't enough time for doing full test but at first sight everything is good.
Thank you one more time for your help and for your job!
