I just discovered a problem with my N5 on CM12 nightlies. For some reason the audio from my ringtones and notifications does not play. I have verified that audio does work for other stuff like music and videos. However when I get a call or a notification its dead silence. I have tried wiping cache, checking all settings (sound and "interuption" settings), updating to the latest nightly and pretty much anything short of factory reset. Is there a fix for this?
