Daniel, thanks for the workaround! It works! I can confirm that JACK not
starting on SOF can be fixed by just setting the period to 1008 or 2040.
I'm on Dell G5.

However, JACK with such a setup is completely unusable for me. All
applications produce noise instead of proper sound, probably expecting a
power of 2 frame sizes. The only setting which helps somewhat is "Force
16-bit" ("works" only for period of 1080, not for 2040) which makes the
sound almost normal, but with crackling distortion.
