It ought to coexist fine with rtirq. I suppose the issue being if they try to set different priorities for the same interrupt handling thread. You could use rtirq for boot (and for setting non soundcard handling threads), and then let udev-rtirq handle hotplugging. I've spotted a bug when there is i...

Hi, I've written a small utility (https://github.com/jhernberg/udev-rtirq) that changes the priority of the thread handling the soundcard interrupt when it detects a soundcard. Prerequisites are either a rt kernel, or a lowlatency kernel booted with the threadirqs flag, and systemd. This works both ...

Yes, IIRC the initial plans for this year was for jack2 to catch up with jack1 regarding the internal clients and the metadata api, and to make it use the same submodules for headers, examples, and utilities. I guess we'll see what happens after that. Looks like jack1 will be put aside and new devel...

I would add that jack2 is under development. Jack1 is in 'maintenance' mode. AFAIK, none of them are under development right now, in fact one might state that jack2 has quite a lot of catching up to do, see internal clients, etc. But AFAIK, development will probably pick up again, and it will be th...

Don't know if it's packaged, but the source is at: https://github.com/x42/lv2vst

FWIW, if you want to use a midi keyboard with reaper then you have to run jack. You'll also have to use either jack1 (which has a builtin alsa/jack midi bridge), or if using jack2 you have to run an external midi bridge, but don't remember the name. You'd also have to connect alsa and jack midi port...

You can just copy the bundle from a mixbus install, to somewhere your program finds it.

Also to keep ~ clean, you can put the license file in ~/.config/harrisonconsoles.

Yes, I've used it in reaper with the lv2vst wrapper.

bfq is another I/O scheduler, see: https://en.wikipedia.org/wiki/I/O_scheduling. Not sure how relevant it is for your use case. IIRC I use deadline myself (which all kernels have). I think with SSDs it's not really an issue. When using HDDs even with BFQ I had occasional xruns, until I figured out t...

Just one note, at the moment 4.14-rt is the development branch for rt where new rt code is tested, while older kernels like 4.9-rt are considered stable. I've not often seen bugs with the dev branch, but maybe something to be aware of.

To achieve lower latency there are a few steps to follow: 1. Setup the priorities. Set the soundcard interrupt to something high like 95, then run jackd a bit lower, say priority 80. 2. Use a lowlatency kernel, and/or even better a rt kernel. Be aware that some hardware/drivers can cause problems, s...

Since we are talking digital playback, the only reason I could possibly think of would be samplerate conversion. Try adding "resample-method = speex-float-10" to /etc/pulse/daemon.conf.

Any other app running presents the same issue as a JS in a browser, it's just a question of how it gets on the computer. Granted us linux users are less prone to running binary blobs (disregarding the packaged binaries most of us install). That malicious code can be also in source code. Hiding some...

The reason I chose Ubuntu instead of Arch is the lowlatency kernel that works with nVidia proprietary drivers. The low latency kernel I could find for Arch is the Liquorix kernel and that takes too long for me to compile, not to mention having to uninstall the nvidia-lqx/nvidia-utils packages to co...

Spectre is arguably the bigger problem... Yes and No. It's main attack vector is malicious javascript from compromised websites, and all the main browsers are rapidly pushing out patches to deal with it by both reducing the timer resolution available and also randomising it - the exploit relies on ...
