Short answer: Install whatever's necessary to place a copy of alsactl
in /usr/sbin, and make sure the file /var/run/alsa exists before
alsactl is run by systemd. If /var is a temp directory, this might
include a shellscript kludge.

Long answer: Systemd represents a huge complexification of Linux, with
all sorts of side effects widely reported. If you would have been
initting with runit instead of systemd, fixing this problem would have
been an easy exercise in elementary logic. There are several good Linux
distributions that don't use systemd to init.

Does your sound do anything funky? Does your sound retain its settings
between boots,  even for applications that use ALSA? If so, the only
concern is these warnings camoflaging more serious warnings. But if
your sound actually suffers in any way, you probably want to fix it.
