My speaker sound just is not working, no sound on phone call, music apps, facebook nothing until I reset my phone the sound is back on! It stays on for a few days then goes back off and I have to keep resetting my phone before making any calls I think this is a software but how to fix it without going back to factory settings, I have used my Bluetooth headset and it works fine but the problem remains after I disconnect my headphone device! Phone is an expira z5 compact

Try to use your phone in Safe Mode to see if the problem remains, if not, it is a third party app that is causing the problem.
If the problem remains the next solution is really performing a software repair with Xperia Companion.
