When I launch Pd and set the DSP going (even if there is no patch open at all) the Mac Activity Monitor shows 'coreaudiod' suddenly jump to using 20-30% CPU and I notice a high-pitched whining sound coming from the computer. Other audio software does not have this effect. Is this normal? If not does anyone know how I can fix it?
Macbook Pro OSX 10.13.6 with Pd-0.51-4
