    Why only support 48000 sample rate? For reasons I haven't debugged, I get more problems on my system when I set my hardware to 48000. And it seems like lower rate might be a tiny bit better for less processing. Is it feasible to support 44100 as an option?

    The OPUS audio compression codec works on a fixed rate of 48 kHz in Jamulus. So it does not make sense to run your audio card with 44.1 kHz. You would need a resampler implemented to support your sample rate which introduces additional processing requirement and also introduces additional delay.

      Thanks for the quick reply. Makes sense. I'll have to figure out why (unrelated to Jamulus, happens separately) my Focusrite 2i2 causes xruns on my Linux system when at 48000

        Please checkout this thread: https://sourceforge.net/p/llcon/discussion/533517/thread/e0f18d2381/. The Focusrite audio interface needs special attention. There is already an issue on Github for that: https://github.com/corrados/jamulus/issues/53. I hope I can address the issues soon.

        Oh, wait. You are saying that it makes trouble under Linux. The issue is about issues on Windows with ASIO...
