Hi,
Had been struggling with getting rid of Xruns based on various
recommendations like switching to low-latency kernel, turning off WiFi,
changing audio interface to other USB ports etc. This is a i5-8400 + 16GB
DDR4 + SSD based system running Lubuntu, and with 128*2 buffer-settings.
Xruns were seen with almost no non Jack applications running, barring say
htop.
However tried the Liquorix kernel based on someone's advise on a similar
topic, and it seems to have completely solved the issue of Xruns. Now I
have perfectly glitchfree recordings, several other applications (some
quite heavy) running. Thought, I'd share with the community here.
Cheers,
BD
Hi,
Had a great time playing around with calf-plugins and doing some live
vocals (except the few rare xruns that still do trouble me). However, I
noticed that while 'Reverb', 'Chorus did not have a byepass button, few
other ones did. What gives ?
Also when a signal is bypassed, does the overall signal-chain latency drop
(because DSP overheads drop) ?

Hi all,
For a sound playback system I'm putting together, based on a Raspberry Pi 3,
I'm looking to have 4 channels of input and output, and to have the system
to run automatically at startup.
For this, I'm wondering how to (best) execute zita-a2j and zita-j2a; I've
tried two methods that don't work:
1. ask Qjackctl to execute the following script after startup:
sleep 5
zita-j2a -d hw:CODEC_1
2. execute this script:
qjackctl (with auto-start)
sleep 10
zita-j2a -d hw:CODEC_1
Executing the zita-j2a manually after Qjackctl has finished starting the
jack server does work.
Any pointers greatly appreciated!
Cheers, Steven

Well, the problem seems to be that there's no dedicated physical USB 3.0 port on my machine, the physical
port act as the one or the other depending on what you connect.
All physical ports have the SuperSpeed symbol, but none of them automatically connects to the
(internal) USB 3.0 root hub if I connect a USB 2.0 device, so I assume there's some logic that
detects whether the connected device is 2.0 or 3.0 and connects it accordingly. Like, when I connect
a USB 3.0 storage device, lsusb shows it as connected to the 3.0 bus.
So I my guess would be, if I use a dedicated (external) USB 3.0 hub, it would be detected as a 3.0 device
and routed to the (internal) 3.0 bus, and thus the devices connected to the external hub would be as well.
But, of course, that's just speculation. I might just get a 3.0 hub and try.

I'll try this. I'd be nice to not have to get them both visible in Jack
at the same time.

Hi,
I've been playing around with an X32 recently, and it starts glitching really fast.
Like, if i start JACK on my internal sound card (2ch) and SuperCollider with 8 to 24 channels, routing all channels to the 2 outputs, everything's fine.
But if I use JACK on the X32 with 8 channels and SuperCollider with 8 channels, it starts glitching as soon as the load increases just a little,
using the same programs in the background (ScSynth, SBCL (Common Lisp) using Incudine for OSC scheduling).
I've found some settings that work ok-ish, but I still have to be careful not to play too many things at the same time. Using the internal sound card,
there's much more leeway.
I'm working on Arch Linux, using the latest RT kernel with all exploit-fixing options disabled (https://make-linux-fast-again.com/). No, I'm not using these
options for my day-to-day work :D .
Has anybody encountered this before ? And maybe knows some way to mitigate this ?
Best,
Niklas
Hey hey,
I am currently experiencing a problem with setBfree, namely that it doesn't
honour the value set for midi.driver and always uses jack.
I have tried putting it inside a custom config, set it in the default config
(in both ~/.config/setBfree and /usr/share/setBfree and set it on the
commandline:
setBfree midi.driver=alsa
with variations:
"midi.driver=alsa"
and
midi.driver="alsa"
No luck. I am running setBfree version 0.8.8. I have just updated to 0.8.9
which still reports as 0.8.8, this is on ArchLinux using the "official"
package.
Is it that my configuration is out of date perhaps? Can someone verify this or
point out a solution, please?
Best wishes,
Jeanette
