when you go to the media slider in the sound settings and move it, it does not make any sounds. also when I play music i can get any music to play. I think media in general is the problem. It's something to do with all playback of audio. Like it's not sending it to the speaker. Because the phone thinks it's playing fine and it gives no errors.
And then, if you reboot the sound comes back. So it seems something is actually causing it
Music plays fine for me via the standard Music app...all audio is fine (videos, music, Netflix, etc.) unless and until I go into the Blur Gallery and select a video. That appears to be where it gets broken (until you reboot).
What media slider are you referring to? In what Settings menu...? Thanks.
