but sometimes it still crashes when booting. I undid the change of "90-alsa-restore.rules" and checked the dmesg log. The error "systemd-udevd[424]: failed to execute '/usr/sbin/alsactl' ..." always occurs. So, I suppose that another problem makes it to crash.
I changed the first line of the file "/lib/udev/ rules.d/ 90-alsa- restore. rules" to
ACTION=="add", SUBSYSTEM=="sound", KERNEL= ="controlC* ", KERNELS!="card*", TEST==" /usr/share/ alsa", TEST==" /var/run/ alsa", GOTO="alsa_ restore_ go"
