I just updated to iOS 13.4.1 on my iPhone 8 Plus. Now, audio keeps glitching with pauses in audio and UI lag.
The audio glitches are most noticeable in listening to podcasts or music, neither of which are really possible now, unless I want to drive myself crazy missing every few words of a podcast. Even as I type this, the keyboard sounds keep cutting out, then a few taps will make the keyboard sound, then another duration of no sound, etc.
I listen to podcasts all day long and deeply regret not researching to see if anyone else was having issues with the iOS 13.4.1 update. I'm glad to know it's not just me, but who knows how long my device will now be unusable for anything involving audio.
If you're reading this and haven't updated yet, do so at your own risk. I don't know if the issue is only for certain handsets, or more wide spread based on yet unknown conditions - perhaps chipsets?
Thankfully I have an old iPhone 6 Plus that I can use as a backup media player for now. Don't know how long I'll be in iPhone purgatory before Apple rolls out a fix for iOS 13.4.1 and how unusable it has made my phone for anything that involves audio.
Interesting, I just noticed the same lag on the Taptic Engine. When I long-press the space bar to move the cursor around, the Taptic feedback lags behind significantly, or fails all together.
