My Z10 had been working without issues until after installing this update a couple of days ago. After either restarting or waking up from standby mode the sound is gone from every application. I noticed that it's an issue with the connection to my Hi sense Roku tv, but not the tv itself. If a restart several times both the tv and the Formuler the sounds eventually comes back, sometimes is one try, sometimes it takes several tries. I know that the TV is not the issue as it works just fine with any other devices connected and changing de HDMI port makes no difference, furthermore when this is happening if a use an app directly from the TV it does work.
