Some changelog details might be related:
alsa-utils (1.1.2-1ubuntu1) yakkety; urgency=low
- Move init script volume settings to new alsactl database
- Put the daemon file in /var/lib/alsa
- Create /run/alsa directory so that systemd services don't fail
(/run/alsa is missing & /run/alsa/ is empty)
* Drop upstart files, Debian doesn't carry them, and we use systemd for
init

Title:
systemd-udevd[409]: Process '/usr/sbin/alsactl -E HOME=/run/alsa
restore 1' failed with exit code 99
Status in alsa-utils package in Ubuntu:
New
Bug description:
This error is logged :
systemd-udevd[409]: Process '/usr/sbin/alsactl -E HOME=/run/alsa restore 1'
failed with exit code 99
note: sound works as expected when the GS session is opened; so maybe
a boot race.
but from a terminal, an other error is found:
