Hi, I use the 2i2 on linux, and you should be able to use 64 frames/period. For USB audio on linux is seems that periods/buffer should be 3. Using thses I get under 30ms overall delay for a server that is 6ms ping away. On a local server (ie. same LAN as the client) with 1ms ping, I get 9-10ms overall delay. This is with high quality / stereo - giving a high bit rate of 900kbps. 12ms ping seems rather high for a local server.

The musicians I work with use Mac and Win, and I use Linux. I concur with Vincenzo's comments. We've had few issues with MacOS. Comparing Win and Linux (Arch Linux in my case), I've not had any issues at all with Focusrite and Audient Evo 4 on Linux, whereas there has been the need to switch drivers ASIO4ALL to vendor's drivers when moving from built-in to interfaces. Also I found it interesting that even with latest drivers and firmware, the Evo 4 seemed to have 4-5 ms greater delay on Win 10 compared...

The odd looking left to right and right to left connections on the input side are to make my mic appear as 2 channels of mono, and still support a second line in for this interface.

This is how it looks on my laptop:

I use Linux extensively, and the quartet I work with use Mac and Windows, so I'm sharing our experience so far. Others may have different experience from us, so your mileage may vary, as they say... Also I'm referring to acoustic instruments, where you can hear the instrument, and not something like an elecric guitar Direct sound can come from open-backed headphones (which let significant amount of direct sound, eg. from a violin), a direct headphone signal on the interface, or incorrectly adjust...

Hi Tom, If you are playing with a microphone you can always use an external metronome This works, but it's worth noting that the person with the metronome hears it in real time, while others hear it with delay, and will try to play in time with the delayed metronome that they hear. One better option would be to have a metronome track played into Jamulus, and everyone hears it with the Jamulus round-trip delay.

Thanks @Gilgongo. I imagine the documentation takes a lot of time. As I learn more where the sources of information are, I will try to get involved in the wiki, especially parts relating to using Linux, which is my primary o/s.

@Gilgongo, thanks for reminding me about the Github Wiki. It's close to what I mean, but I see it more like a cookbook than a reference wiki. It is very useful, and thank you for helping populate it with information. My small requests are: Treat it as "The Official Jamulus wiki", and promote it so that it becomes the point of reference for Jamalus information. Now when I search (google) "jamulus record session", I get several discussions, blogs, together with the github wiki somewhere around #3....
