I had the same problem (phone not audibly ringing) on an Aquaris E5 running Ubuntu 15.04 OTA 11.
I also had another 'irritation' in that some websites overrode my volume settings. Turn the volume right down, so as not to disturb others while watching video clips, then open up YouTube in the browser and start watching video. Despite the volume being right down audio blares out at full volume and you have to turn it down again. It turned out that the two were connected. If you leave the webpage with audio turned down then you loose audio on the phone's ringer. To get audio back open the web page up again, turn up the volume so you can hear things and then close the tab for the site. The phone then rings as normal. It looks like the website is forcing full audio and if you leave the page having turned the audio down then you are stuck with no ringer volume. I know it sounds weird but try it. At least it is a possible workaround and the 'mechanism' could be the root cause of the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1533251 Title: Ubuntu phone / Aquaris E5: no ringtones when receiving calls, no sound when receiving messages; no sound on speakers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/indicator-sound/+bug/1533251/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
