That alert triangle exists to replace this extremely common warning dialog with something that doesn't jump in your face and demand your immediate attention. What it means is that your kernel was compiled with a system timer resolution of 1000 Hz instead of 250 Hz or whatever it is that we prefer. In of itself, this doesn't have anything to do with realtime or low latency one way or the other, and it's strictly a measure of kernel timer resolution. They changed the default resolution a few years ago, so this is a sign that you have a generic kernel that has not been tweaked in any way for Linux audio. This is not an ideal situation, but many users go on running a kernel like that for months or years without perceiving any particular deficiencies in Rosegarden's performance. In theory, the timer resolution is too low to reproduce MIDI accurately, but in practice, I'm not aware of anyone who has ever reported actual real world problems doing so. I would put it in the category of: Fix it if you can readily do so, and ignore it if you can't. Since Ubuntu Studio is no longer shipping with a -rt kernel, you don't have any sensible options. If I were you, I would just ignore it and go on. Ubuntu Studio will sort this kernel business out eventually if they want to stay alive as a Linux audio distro. If not, there are others. -- D.
