Hi all -
I hope I'm in the right place. I've tried a few different forums and
message boards now with no response.
I am attempting to run an AudioInjector Octo (a simple 8-channel audio
hardware card attached to the GPIO) on a Raspberry Pi 4, running the
Raspberry Lite OS.
My understanding is that ALSA manages AudioInjector - but that I also need
jackd to send audio from my software (SuperCollider) to ALSA.
While ALSA seems to read the AudioInjector without trouble, I seemingly
cannot get jackd to boot. I am new to all of this, so there may be many
things I have not yet tried.
Namely, the following line of code causes my terminal prompt to freeze:
jackd -d alsa -r 44100 -P hw:2
Any pointers would be a great help. Thanks!
The external USB midi port shows up in the qjackctl graph.
The midi dongle works fine in other Windows apps. It was also working
with jack not long ago since then I have upgraded the PC and reinstalled
Windows.
Windows version is 10.

Hi
What is the best strategy for compiling a software on Windows using tha
Github's actions?
1) Decalring as windows, downloading the .exe installer, compiling my
software using MSVC?
2) Declaring as Ubuntu, aptget the sources, compiling them with, for
instance, mingw, installing, compiling my software?
Thanks
Hello,
I cant find much on these cards online, it is working inside Jack, BUT - I have 4 capture / input devices, and can only see two.
When I try and add more I/O my qjackctl application refuses to talk to the jack dbus and crashes out.
I really would love to get the multi channel working, but just struggling with it.
Will provide more info if anyone can help or has these cards, I would love to get more information.
I can confirm if I use the device directly I have access to all 4 inputs, but I can only use the source once, which is why I am keen on Jack as I need more applications listening to the inputs for various reasons.
Anyway, any help would be awesome.
Thanks in advance,
Chris :)
Hey Guys
How do you use jack with MainStage and logic together? it doesn't work like it used to.
Sent with [Proton Mail](https://proton.me/) secure email.
I need to use jack to generate monitoring from my microphone to headphones
and control the volume of the voice. I have a macbook pro and installed the
jack package and it works fine with qjackctl on my mac. But I would like to
be able to do the same without using qjackctl, as the idea later on is to
create a UI with the minimum controls needed to connect the microphone to
the headphones and control the volume.
According to ChatGPT, to start the server I should use the jack_control
start command, however this command is not available on the command line. I
installed jack with the package I downloaded from the official site.
I can't find any documentation about the commands I need to manage jack.
I would appreciate it if someone can give me indications on how I can learn
to use jack from the command line.
