Hi, this is my first (or maybe second) time I write here, anyway... I am such a user. My setup is a bit complex, since I use three machines connected through a Gigabit Ethernet link, and all of them run Linux over a Ryzen CPU. The “master” workstation is equipped with a Ryzen 5 2600X and the audio interface (for now a lousy Behringer UCA202, but I would like to upgrade to a Focusrite soon). There is also a “slave” laptop, a HP db0035nl which, at the time I bought it, was one of the few to sport an AMD processor, namely a Ryzen 5 2500U. The last one acts mostly as a router and a file server, but is ready to be used as an additional host for virtual instruments. CPU: Ryzen 5 2600 (not X). All the computers run Fedora 30, with the latest kernel available (5.5.10), except for the laptop, which uses a realtime kernel, version 5.4.24 (the “ycollet” RPM, not the CCRMA one). A JACK server runs on the master, at 48kHz, 128 the buffer size, 2 periods. Here I run Ardour and Carla, which also hosts Kontakt through the WINE bridge. In addition two instances of NetJACK 1 accept connections from the other two computers. So far this setup looks (and sounds) quite stable, espscially on the “master” side, which after a work cycle shows about no more than 300 xruns, none of them audible. The laptop is a bit slower, there are some synths on it, and a keyboard controller connected through USB. The purpose of this setup is to use it in live situations. The RT kernel gives it a greater stability (less xruns and less errors), while the 5.5 series has quite a few annoying bugs. The third machine has the necessary disk space to hold the audio samples, served through NFS. > If so what is your recommended setup? Well, this configuration is less than one year old and I am still learning how to use it at its best. Anyway, so far I can tell that I’m quite happy with it. but YMMV. cheers Francesco Napoleoni _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
