Today I worked on a little bug in SPDIF-in, and I noticed a problem with radio interference:
I had a Teensy 4 with a short program which uses SPDIF-OUTPUT (and a second with SPDI-IN - but that does not matter here)
If I connect a 10cm patch cable to any of the three SPDIF-Outputs, my DAB radio - 2 meters away, with a telescope antenna - stops receiving! This is reproducable.
I never noticed this with a Teensy 3 (but quite possible, that it happens with the T3, too)
How can I fix that?
