Can someone help with an audio problem?

I’m still having issues even after the 3.1.1 update.
My music will play perfectly fine over WiFi, but will not play over 4G.

@Goldn3agle: there have been a few important fixes on 3.1.4, which is making its way to the Windows Store. Please open a new thread in case you see that the 4G problem is not fixed there.

Plex 1.4.1.3362 and windows 8.1 mp3 files will not play on pc but will on other devices
I posted the log files a week or so ago on the plex pass general discussion forum. The log files are attached. I think Plex is stumped.

Could someone pls say if Plex thinks this is fixed? Did any of the posters get it working on PC? It never starts to play. I am using the plex player app on my home theatre PC and it cant find player which is the htPC running app. The PC app is probably only encoded to send your library to another player perhaps? It plays video to my lg TV but cant find a player for the audio?

I am sure PLEX would have solved this by now so is there a link please.

Thanks

I have two separate windows 10 laptops. It works on one but not the other. when I select Play, it just says playing with the time at 0
