I believe this issue has started happening since the UI update. Audio is fine when the display is on, but when I turn the screen off the audio through my earbuds (wired) becomes extremely choppy, slowed down, and crackling. Sometimes it will go away for a while, and I think it crops back up if I restart my phone? I've tried a lot to fix it. I tried using the Samsung members app to report it, but the feedback seemed to think it was a Bluetooth issue. I don't use Bluetooth, so that wasn't exactly helpful. Any help or suggestions would be greatly appreciated.
