[Reason found - probably]System sounds is jump to very low volume after last system update (1.0.7.16).
Few days I'm trying to figure out what cause to this problem, but without success. When it happens it really hard to heard notifications, calls, alarms... I didn't install any new apps in this period... For fix this problem, only running restart of pulseaudio command can restore sounds back to the real volume (systemctl restart pulseaudio.service). Problem is if I don't know that problem is already exist, I missing calls, messages, alarms... It's really not good :( Someone experienced similar problems ? Any advice ?
