Hello everyone,
I'm new to this list and also new to Linux.
I am a PhD student working on a research project with hearing impaired people.
For
our research studies we want to realize different audiological tests
with a virtual acoustic sound system. The program we use for rendering
the virtual acoustics runs in Linux.
In our lab, we have a Fireface
802 sound card from RME. But RME doesn't offer support in Linux and
unfortunately doesn't provide drivers.
I
run the Fireface in ClassCompliant mode and it is connected via USB to
the computer with Ubuntu Studio 20.04 LTS as operating system. Basically
the Fireface works, I can use 8 output channels for my sound playback
via Jack.
But the problem is that I actually want to get playback
from 12 loudspeakers in our loudspeaker circuit. When I start Jack, it
displays 22 output channels, but as I said, only 8 playback channels are
playing sound.
Could this be caused by the snd_usb_audio driver? Or how can I assign the output channels directly?
About any suggestion for a solution I would be very happy!!!
Best regards,
Sebastian Roth
Hi,
I'm using jack for years with my Focusrite Firewire device, formerly
with Ubuntu Studio, now with Parrot Home.
Recently I changed my DAW from Windows to Linux, using Ardour and Bitwig.
For my old Windows VST plugins, which do not run with Wine, I use a
QEMU/KVM virtual machine with Win7.
To connect Host machine and VM, I run jack_load netmanager on the host
and jackd -dnet -P12 -C2 -i1 -o1 -l1 in the VM.
First they could not connect, but I suspect jack_load netmanager to
listen only to the main network device eth0, but not the VM's network
device virbr0. I found a workaround with smcroute; I configured it so it
reroutes the Multicast messages from virbr0 to eth0. This solved the
problem.
Now I can connect the VM in/outs with qjackctl on the host, and I can
play the Win7 VST plugins, as if they are running in Linux; perfect!
But a problem with jack transport appeared:
If the VM is not running, jack transport on the host is working as
expected; click on the play button in qjackctl, and the counter runs;
click again and the counter stops.
If the VM is running, there is a delay of about 5 seconds from click on
the play button, and the start of the counter. Stopping the transport
works immediately.
So this makes recording difficult.
Qjackctl in the VM does not show jack transport running/stopping anyway;
it can be started/stopped independently.
With verbose messages on, this message from the host jackd appears
regularly, no matter which transport status:
Jack: CatchHost fd = 74 err = Resource temporarily unavailable
After click on play button, but counter not running, repeatedly:
Jack: JackNetMasterManager::SyncCallback returns 'false'
Jack: CheckAllRolling ref = 8 is not rolling
When counter runs, repeatedly:
Jack: JackNetMasterManager::SyncCallback returns 'false'
I assume that there exists still a network related mismatch between
jackd on host and jackd in the VM, but I was not able to identify it. So
I need some advice about jack transport and net mode.
Btw, an option for jack_load netmanager would be nice, telling on which
network device to listen. So people get aware of this case and can solve
it without smcroute.
Thanks,
S.Auerochs
Dear all,
I have written a jack client that uses an APCmini as a mixer and provides eight
inputs/outputs and eight VU meters through it. CUE, PFL and transport control are also
provided.
I would like to check the code into git - what do I have to do ?

I every one,
I'm new with jack . Just dowload JACK 1.9.18 macOS-universal
<https://github.com/jackaudio/jack2-releases/releases/download/v1.9.18/jack2…>.
to use it with my mac book pro M1 (big sur).
Download also supperlooper.
When i open jack, it shows my interface (sound card UAD appolo) but when i
open superlooper, it says "connection error, no response from superlooper"
I tried to open other software like uad luna or garage band, but they dont
show in jack neither
