+### State file
+
+Some values may be set only one time by UCM and then they are saved to
+the global ALSA sound state file. Please, make sure that this state
+is cleared, if you have an issue.
+
+Commands for standard systemd setup (relogin is required):
+
+```
+systemctl stop alsa-state
+rm /var/lib/alsa/asound.state
+systemctl start alsa-state
+```
+
