I think I have the same but though my phone's sound works just occasionally sometimes garbled.
Whenever there is no jack plugged in and I start playing something dmesg prints [ 416.722213] lipeng debug|[Sound_Speaker_Turnon] Speaker_Volume: 0 I also appended a version of 'pacmd info' when it's working and when it's not working, but I can't see a significant difference. So I think the problem is lower. ** Attachment added: "info_working" https://bugs.launchpad.net/ubuntu/+source/indicator-sound/+bug/1533251/+attachment/4602560/+files/info_working -- 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
