Ok, finally the bug returned back. Via ssh i made a full dump of the .cache/upstart directory, so - this time - i have a full log availability :) and some other info:
@Bill >When the phone is in this state, do any other sounds play correctly? For >example, can you play music from the music-app or try to change >ringtones and preview them from system-settings? I tried both, listen music and change ringtones in system.settings: no sounds. @Tiago >Could you run the following command and paste the output for us? >zgrep "Failed to get current playback position" $HOME/.cache/upstart/* That command still reports no results, so, i believe this is not a duplicate of that in comment #3 (at least is slightly different). The error, this time, blown out when i'm trying to figure out reasons i can't play some kind of videos as reported in bug 1512090, so, surely something has crashed somewhere and this prevents sessions to be restored. There is a thing i don't full understand: in comment #4 Bill mentions a workaround, then, is this workaround included in OTA-8.5? If so, then it doesn't solve this bug. Now i'm going to attach some logs. feel free to ask the full upstart dump if useful to solve this bug. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to telephony-service in Ubuntu. https://bugs.launchpad.net/bugs/1512132 Title: sometimes no ring for incoming calls.
