From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Question about JACK audio interface. (self.linux)

Hi everyone, I got my e-drum kit to successfully work in reaper, using yabridge for the VSTs. Shortly after, I found another way in which linux audio is different than windows. While using reaper, I am unable to play audio from any other source. Through research, I discovered that it's because I'm using ALSA and that I need to use JACK instead. I looked up guides on how to setup JACK and qctl and was unsuccessful. I came across a video explaining different problems with JACK and it mentioned that using a pcs built in audio card may not be able to handle the audio in JACK. Right now, it seems like I need to come up with a different solution. But I thought I would ask here and see if I have any other options. I don't have any external dacs, but I do have my desktop pc that still has windows so I'm thinking of giving up on using my linux laptop for my music needs.

Tldr- want to use reaper while watching YouTube vids. Alsa won't allow that, and jack isn't working on my laptop.

Maybe look into PipeWire, Reaper in jack mode works fine connected to PipeWire for me, without any of the problems you mentioned.

It is quite possible that your desktop audio already uses PipeWire depending on your distribution, you would need to look at latency settings if you want live playback.

I'm using linux mint. And sorry, but I'm a noob wktu audio software. I'm pretty sure I already have pipewire, but I'll double check. Are you saying to try pipewire instead of qctl?

There is no need to use external programs anymore unless you want some kind of special behaviour (like the plugboard that qjackctl gives you). Pipewire has reimplemented Pulseaudio, ALSA, and JACK, which at one point in time were 3 separate projects.

Pipewire emulates all 3 seamlessly. So when you run a program through JACK, pipewire picks it up pretending to be normal JACK. To the program, it looks like you have a standard JACK server, but on the backend, it's running through Pipewire instead. You should get the same low-latency too.

Do make sure you have pipewire-jack or the equivalent package installed.

Would you recommend JACK for low latency inputs and allowing me to play along to songs on YouTube? I was able to get it work with pulse audio but the latency was too high.
