'No sound' in Xperia X F5122

[Chishti]

Whilst making a video, suddenly the video could not record as the audio was busy else where  Now I do not have any sound in the phone. I have run all the tests, updated and repaired the software through Xperia Companion  , restored to factory settings but still no sound. Any suggestions will be appreciated.

Try a good software repair using Xperia Companion.
