Would be nice if you could share your experiences with different sound devices. I have a relatively expensive and high quality sound device (Scarlett 18i20 Focusrite) which works perfectly (Win & Mac). In corona times my band members also want to get a sound device, which shouldn't be that expensive. Many thanks again to Volker for his great work.

If you want to have a cheap interface which gives you good latencies then you should try the Behringer U-Control UCA202. But with this interface you just have cinch input so you would most probably need an analog mixer to support, e.g, and instrument and microphone at the same time.

The Behringer U-Phoria UM2 is the cheapest interface I know. And gets good reviews. It is a 2-in 2-out audio interface with one combined XLR and instrument input, and one instrument-only (6.3 jack) input. And it can send phantom power (48v) to the XLR for mics that need it. The UM202 is more expenisve, and has two combined XLR/Instrument inputs and a higher sample rate. The later is not needed for Jamulus, though.

We have tested both USB 2.0 and Thunderbolt interfaces and the performance of the latter was noticably better (however, hard to quantify as we did not measure it independently). We now have a Focusrite Clarett 4Pre Thunderbolt on one end and a Zoom TAC-2 on the other. Both work perfectly with overall delays of < 30ms, even under 20ms possible. Unfortunately, Zoom has discontinued the TAC-2 which was an inexpensive alternative to the Focusrite.

I use a Yamaha AG03 with a Nord 6 Electro going in on channels 2/3, USB in/out to my Imac, clip mic for chatting going thru the headset mic input to channel 1. I had the challenge to set up my Ipad as a source for IrealPro or else music sources for the cases when no bass/drums are present and the simple solution was to input it thru AUX ... needed the respective adapter from Lightning to 3.5 "Klinke" for that, though. The latter initially created some background noise when power cable was attached; but turned out problem was neither cable nor adapter, but a three port USB-power adapter.

I think I saw in another thread that there was a Wiki page for hardware (audio interfaces) but now it is gone. It would be great if we could get a constantly-updated list or wiki going again somewhere, is that a possibility?

But you're right it would be good to maybe have a separate page listing tested stuff in more detail. I'll set that up and encourage people to add to it.

What is considered as a low latency sound interface? I use XR18 and got 20-30ms latency (when I subtract overall latency minus ping to the server). Is that considered as good? Any techniques to get it lower?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
With my XR18, I set the sample rate to 128. I tried 64 in the new version, but that made it sound like I was under water. My interface latency is about 5ms. Also make sure you are using the 4.59 version driver if you;re on Windows.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I will try on Windows, but now I'm using macOS Catalina. I saw plenty of issues with its Core Audio. First, I cannot set sample rate, and second, latency seems too high when compared to your case. I've never had latency lower than 20ms, as same as when I don't even use my XR18 as a audio interface.

I'm now on Windows machine, while having linux machine running the server in the same local network. I see that my audio interface latency is around 5ms, but overall latency is still about 20ms. Is PC hardware causing additional latency? I've got i5 6200U processor with 8GB RAM.
The rest is your PC, your network, your router, and the linux machine with the server. 20 ms is okay for a local set-up. You might try to use Quality of Service on your router to give UDP traffic priority, give both machines fixed network addresses (IP-numbers) and to start the server software with the highest priority (both CPU and I/O) on the server. But it will not have a lot of impact.

I'm getting good sound reproduction for clarinet by using a Piezo barrel pickup connected directly to the computer microphne input.. I have disabled the integrated mic. I listen to myself on speakers plugged into the computer inputs. Pure sound reproduction. and no ambient or extraneous sounds. No headphones or actual microphones needed. Piezo pickups available online for most instruments.

Hi,
Really cheap and often allready existing solution that works perfectly for me (Imac 2019 Catalina). ZOOM H1 (N or not N) setted as USB audio after USB conecting. The mic pair on the device can be enought for a singer or acoustic instrument player ... You can even use the headphone output of the device (not bad at all) if you wish.

Have fun !

Hi Rob - there is a very small list of known good hardware on this page:
https://github.com/corrados/jamulus/wiki/Hardware-Setup
But you're right it would be good to maybe have a separate page listing tested stuff in more detail. I'll set that up and encourage people to add to it.
I've split out a separate page for this here. Please add any new info you have:
https://github.com/corrados/jamulus/wiki/Sound-Devices
Fantastic, I've added a couple to the list, and will add more as I help others get connected.
Thanks!
How can I edit this wiki page? Can you grant me access? Do I need to become a collaborator?
I think you just need to have a Github account, and also be a personal friend of Linus Torvalds. But that might not be a requirement any more.

Strange, I'm also using a XR18 and getting a very good sound at a sample rate of 64.
The cause must be found elsewhere, I gues.

hello´
Could I ask what is the 4.59 version for Windows users,
thanksPierre
Is there a program to measure the lattency of the settings and devices? It should play a click and wait for the responsee at the mic.
There is a hardware (and network) latency checker as part of Jamulus OS you could try:

That is a great idea. zoom have brilliant mic quality.
I use a Tascam DR-40 as an audio interface with Jamulus, and it never occured to me to use the mic on it as well! I'm pretty sure you can. Doh! And I bought a separate mic.
I'm an idiot.
