Re: USB Audio Interface JACK Xruns on Linux but not on Windows

It works on your laptop. Probably you plugged the soundcard into a USB 2 port. So it may be USB 2 works, rather than the laptop.

You could move your mouse, keyboard and everything else onto USB 1 and use USB 2 for the soundcard.

Re: Hello Linux Musicians

You don't need a "special" (i.e. badly supported) distro for that. You've said this in a few posts. I think it's misleading. What support are you talking about? Do the Ubuntu forums have specialised pro-audio hardware support? It seems unlikely considering the number of people who turn up...

Re: USB Audio Interface JACK Xruns on Linux but not on Windows

You could try using your USB soundcard as an input and the internal soundcard as an output.

Re: USB Audio Interface JACK Xruns on Linux but not on Windows

I see. It is a while since I used QjackCtl. :)

So @Drumfix is saying the problem is with the ALSA driver for your hardware, which is a kernel module.

Re: USB Audio Interface JACK Xruns on Linux but not on Windows

It looks like it's what Drumfix said then. Before you investigate patching the kernel -- 'duplex' mode is for using a different input and output device. If you don't select 'duplex' then the same device is used for input and output. You also mentioned you had enabled D-bus. You could try deleting ~/...

Re: Guitarix doesn't "catch" my Guitar's sound but Audacity does

On the Reddit thread a relevant link is dead. The thread addresses using two sound inputs -- an interface, and a guitar pedal that I'm guessing connected with USB. This isn't relevant to your setup.

Are you using Qjackctl? You will need to make connections in the 'connect' or 'patchbay' windows.

Re: EZDrummer alternative?

Linux has some drum machines and drum samplers. What the OP wants is a robot drummer. The only software I can think of is Backup Band :

I've never tried it, but apparently it does have robots.

Re: Presonus Atom Linux Compatible?

I saw this :

https://www.akaipro.com/lpd8-lpd8

This says it's class compliant and no drivers are required. That will be as plug and play as Linux is capable of. :) Even if you don't get that one it shows such devices do exist.

Re: USB Audio Interface JACK Xruns on Linux but not on Windows

That looks good. Your soundcard has the highest priority. You could raise it to 95 by editing /etc/rtirq.conf with RTIRQ_PRIO_HIGH=99 and lower the priority of all other interrupts with RTIRQ_RESET_ALL=1 I don't think that is what is causing an Xrun every 50 seconds, though. To diagnose that you cou...

Re: Worse performance when power supply plugged in!

Is it correct that I set the realtime-priority for jack in limits.conf and the one for the soundcard with rtirq ? limits.conf is a global maximum. The priority of JACK is set when you start it. On Cadence there's a box to set this, there will be on QJackctl too. rtirq sets the priority of the sound...

If the first command outputs nothing threadirqs isn't loaded. To load it edit /etc/default/grub with sudo . Add to this line : GRUB_CMDLINE_LINUX="threadirqs" Now regenerate grub.cfg : sudo update-grub You'll need to reboot before that takes effect. Before you do that edit limits.conf . Ad...
