Sonic Pi & Octo Sound Card

[sonicpi]

Hi there,

the newest version of Sonic Pi (3.0.0) supports multichannel audio. You have to upgrade the RPi to "stretch" to run it. I did that. I also did the "easy automatic setup" described here: viewtopic.php?f=9&t=1222

Octo sound is runnig, i tried this with sox and an 8 channel text wav file.

Problem is how to route the sound from Sonic Pi into the octo... You have to change one line of code in the ruby source of Sonic Pi here:
https://github.com/samaaron/sonic-pi/bl ... al.rb#L359
( "-o" "8" instead of "-o" "2")...

Sam Aaron said, you should do the routing with jack. So i openend qjackctl. In the connect window, there are 8 outputs from sonic pi as expected. But there are no sound card inputs, just "playback 1" and "playback 2".

I gues this is the problem. What can i do to see the 8 soundcard channels in the connect window?

Thanks in advance

OK - I did a test on a fresh install, using the new installation instructions, which disable lxpanel's volume plugin and remove pulseaudio. They also setup a .asoundrc file.

As a test, I then start jackd like so :
jackd -dalsa

I look at the available ports (either in qjackctl or like this) :

Code: Select all

pi@raspberrypi:~ $ jack_lsp
system:capture_1
system:capture_2
system:capture_3
system:capture_4
system:capture_5
system:capture_6
system:capture_7
system:capture_8
system:playback_1
system:playback_2
system:playback_3
system:playback_4
system:playback_5
system:playback_6
system:playback_7
system:playback_8

OK - all looks good.
I shutdown jackd, startup speaker-test for a quick test and all good :

Code: Select all

speaker-test

I start sonic pi - but it hangs ? Is there a special way to start sonic-pi ?

I downloaded the deb file from the sonic pi webpage :

Code: Select all

wget http://sonic-pi.net/files/releases/v3.0.0/sonic-pi_1_3.0.0-armhf.deb

Before I install, I make sure my system is up to date :

Code: Select all

sudo apt update
sudo apt upgrade

The installer complains about missing dependencies, so I fix it like so :

Code: Select all

sudo apt -f install

I install sonic pi again :

Code: Select all

sudo dpkg -i sonic-pi_1_3.0.0-armhf.deb 

It still complains because it is missing required packages - which aren't in the raspbian release (jessie).

I fallback and try to install 1:2.11 ... but when I install that, and try to start it, it hangs.
Not sure where to go from here with sonic-pi.
