Out of interest - with your real time kernel - how many frames @ what fs is the lowest you have been able to use ?
Just tested fs 96000 Hz with 32 frames which gives ~50% CPU to just shuffle audio from input to output, but I expect the total latency to be below 1 ms, or just there about. For my application 48K is enough, and 64 frames gives ~10% CPU which is a reasonable CPU/latency compromise.
So I kinda got sucked in to building Zynthian a new distro. But it technically comes with a web interface that lets you set up the audio injector, and jack. So perhaps we can merge those projects together.
