I was able to reproduce this finally. It is a matter of killing media- hub-server:
pkill -9 media-hub (this has the same effect as a media-hub-server crash). media-hub-server re-starts, but it looks like not all the system recovers and re-connects to dbus-interface. Voice calls ringing, telegram notifications and videos/music still sound, but SMS notifications and screenshots do not emit sound anymore. So we have here: * A media-hub-server crash (could somebody please check if they have crash files for media-hub-server in /var/crash?) * An issue with reconnections to media-hub, for: 1. SMS notifications. telephony-service-indicator is the responsible for them 2. Screenshot sound. unity8 is the one emitting it Recently there was an effort to make media-hub *client library* resilient to media-hub-server crashes, but it looks like that has not been enough for this case. However, I am not sure if we can completely restore transparently from the library or we need that indicator/unity8 to be ready for media-hub crashes and be able to re-connect. ** Changed in: media-hub (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1544477 Title: No sound notification for new SMS (Ubuntu Touch) Status in Canonical System Image: Incomplete Status in indicator-sound package in Ubuntu: Incomplete Status in media-hub package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Incomplete Status in unity8 package in Ubuntu: Incomplete Bug description: I noticed for last 2-3 days there is no sound notification for a new SMS, but there's a blinking green LED notification. Also in the indicator menu the envelope icon turns green and the new SMS is listed as usual. Things are working alright for Telegram, Gmail etc. (sound+LED+indicator menu).
