Linux on the desktop

Sorry, missed this message. I assume/hope you’ve figured it out by now :wink:
The easiest way is to check the tree/package history, if it’s older than 2015 you’ll have to make do with the changelog. I don’t know of a way to get this info otherwise.

Little victories.

I think I’ve managed to get a parallel jack2dbus / pulseaudio setup working. The builtin motherboard output is used by pulseaudio, and my USB sound card is used by jack2dbus.

But… by using

load-module module-jackdbus-detect channels=2 connect=false

in my, I can route audio from Pulse to Jack (and vice-versa), but not by default (connect=false), which makes it easy to send audio from an individual app to whatever…


Not sure if I should post this in a separate topic, but this might of interest to some


I’ve outgrown my self-imposed limitations of only recording live mixes into a stereo cassette recorder now that I’ve been using a guitar and piano with synths. It’s time for…digital multi-track!

I’m committed to Ardour for recording and editing. I’m not too up on pro audio interface hardware. Looking for something that has a USB connector, 6 or more analog inputs, two mic/instrument preamps and obviously, jack support.

A friend recommended the Zoom R16. Anything else?

Also, I’m thinking of a used MacMini for the computer part. There’s also the Intel NUC. Would a laptop with a touch screen be an alternative?

I had been looking into similar stuff myself some time ago and I hadn’t found much praise for the R16 online. Most people complain about the converters and preamps. Might be worth having a deeper look.
What some people recommended was the Cymatic Audio LR-16 (discontinued, but should be possible to find second hand)
Or you might look into a K-Mix since you’re going to have a computer attached anyway.

I’m borrowing a Zoom R16 so I’ll check out the converters and preamps. The Cymatic thing seems cool but they literally removed the record feature in the same product design. I wonder if that’s because the discontinued version had trouble recording?

The K-Mix looks great. The product download page only provides macOS and Windows links, but I assume it’ll work fine as a USB class compliant interface.

update: Confirmed Zoom R16 is compatible with some Linux kernels. Not really compatible with macOS 10.13.6, despite providing a macOS driver download.

I am pretty happy with my Cymatic Audio Utrack 24 :slight_smile: Got the adat card for it as well. It is not a perfect device but it does the job well!

I have the R24 which works fine for me under linux (though it mostly lives as a standalone recorder in my bedroom) – maybe a newer kernel would do the trick? I’m running 4.18.9 on the laptop I use the R24 with, but a raspberry pi running raspbian (with an older kernel) doesn’t work with it.

I can’t say enough good stuff about MOTU’s ultralite AVB though, which works great with linux (at least a recent kernel, I haven’t tried with older ones) has great preamps, but isn’t a standalone unit, and it’s a bit pricey.

Though I haven’t used them myself quiet a lot of people seem to recommend/be happy with the current Behringer X air series (XR12, XR16, XR18). They are obviously digital mixers and need software to be useful, but since you’re using a computer anyway it might make sense depending on your preferences regarding how you like to work.
They have pretty good Linux support and have Android an iOS support as well in case you want to use it with those OSes.

Apart from that, any USB device that’s supported on iOS should work because they have to be class compliant for that.

again not sure if this On Topic but i have been having getting amazing results with BitWIg on linux for my quasi ableton fix but someone recently reminded me of and i got a very nice working version of Qtractor which is works fabulous. I also am embarking on a recording project over the web with folks in disparate locations sharing tracks and overdubs and i found that the linux BETA of Reaper is just beautiful and works dreamy.

I also recently got a cheapo Behringer X1222 that works perfectly with my linux setup i mix 12 channels to stereo for my mix [i do the mixing on the device and i do not need individual tracks so it’s perfect] it shows up in jack as HW:CODEC and it a wonderful surprise.

nice little tool that works great as a standalone recorder, also with cheap usb drives. Very simple and straightforward to use. Only does panning and -10dB pads. No mutes. Good line mixer and recorder for people who don’t know and don’t care about mixing and recording (me). Haven’t used with computers. Requires floating TRS cables as its designed to connect to the mixers inserts.

I’m using the Focusrite Scarlett 18i20 with Ardour on Ubuntu Studio, and very happy with it.

Hey there, y’all. Anyone got jack (specifically jackd with proper realtime configs and security configs :confused:) running on Arch Linux? Figured it’d be nice to have something with specific mention of Norns development, too. I’d love to give it a shot. Might be a nice resource.

I just have xorg and i3 and PulseAudio routed to a cheap USB soundcard. I want to use Jack and a whole bunch of software (I’m okay writing small scripts or something to handle the management) but I can’t seem to get the damn thing booted :disappointed_relieved:.

Even just links to resources that have worked would be great. Work is nuts and I only have so much weekend time to config and so little time to create! :smiley:

I don’t use jack via pulseaudio – it should be possible to rig up via one of these methods though:

But starting jack2 (I’m using the jack2 package, not the dbus variant) with alsa as the driver (alsa-lib, alsa-plugins, alsa-utils, alsa-tools and alsaplayer are the relevant packages I have installed right now) has never been a problem for me on arch. I still use qjackctl most often to start it standalone and configure it for a new hardware device, but there are a lot of neat new utilities like cadence that might be worth checking out.

@lazzarello and I set up a workstation with i3, jack, and ardour a while ago. If you’re using the USB sound card as the primary device I’m not sure you want to hook it up to pulseaudio? We did it with Cadence and Claudia directly working on the (in our case, FireWire) audio interface.

What are you trying to run / what’s not working?

to be honest, I need to find a compatible interface but cant justify it right now

I’m just trying to get jackd to start with all the correct realtime permissions.

What did you try? What’s not working?

Arch Linux has given great contributions to documenting the distro. There’s a whole wiki page on Jack.

Pulseaudio is useful but not required to get realtime sound from jack, especially if this is a Norns environment. There’s a bridge between jack and pulseaudio so you can do clever things like route audio from Firefox or Chrome to anything else in your jack connection graph. Latency is…well, bad which is expected for playing audio over wifi over internet.

Pulseaudio is useful but not required to get realtime sound from jack

@lazzarello sorry, but I have to disagree with this. Pulseaudio is neither useful nor required to get realtime sound from jack. It actually might be harmful, since jack requires exclusive access to an audio device to work reliably. See for more details on using them together (TL;DR: it’s best to avoid that).
