Thank you for your bug report, that's not a bug though, silent mode is not "muted", see https://wiki.ubuntu.com/Sound#Silent_Mode
"When Silent Mode is on and you are using the internal speaker, the phone should play only sounds that you have explicitly requested. For example, alarms, music, and sound from videos should play as normal, but ringtones, message notification sounds, and interface sound effects should not." ** Changed in: ubuntu-system-settings (Ubuntu) Importance: Undecided => Low ** Changed in: ubuntu-system-settings (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1509698 Title: Mako: sound plays in silent mode !
