Instead I should use "select". Incidentally, the leds behave the same in either case which was what threw me for a loop. Also, I was able to get udev to load my profile by modifying the file /lib/udev/rules.d/90-pulseaudio.rules. Initially, I had written my own 91-pulseaudo-rme-babyface-pro.conf which did not work. Maybe udev does not want to reconfigure a device that was already configured? /Allan -- Allan Wind Yaxto - Runs My Business <https://yaxto.com>
