[AudioI] AudioInjector Octo on Buster Lite

[cx b]

Hi there -

I'm currently trying to get AudioInjector up and running on a
Raspberry Pi 4, using Buster Lite and running headless.

I'm a little new to this stuff, so I apologize for lacking clarity.

My understanding is that PulseAudio is the default driver currently
and direct access to ALSA has been hidden, which seems to be creating
problems. In any event, as of now, I am unable to get Octo identified
and running.

Going by the manual install on the Git, here is my log:


pi at raspberrypi:~ $ sed -i 's/\=volumealsa/\=REMOVEvolumealsa/'
~pi/.config/lxpanel/LXDE-pi/panels/panel
sed: can't read /home/pi/.config/lxpanel/LXDE-pi/panels/panel: No such
file or directory

'rpi-update' should only be used if there is a specific
reason to do so - for example, a request by a Raspberry Pi
engineer or if you want to help the testing effort
and are comfortable with restoring if there are regressions.

DO NOT use 'rpi-update' as part of a regular update process.

After this, I reboot.

I'm not sure where else to identify or test the install.

My goal is ultimately to run this interface with SuperCollider and my
following steps were to use this tutorial:

Ultimately, though, SuperCollider could not identify Jack or the Octo.

Any advice would be greatly appreciated.

Thanks.
