I came across this problem when checking out usb wifi when moving from 5.0.013 to 5.0.014

However, this is not a wifi issue.

To cut a long story short, playing a recording of last week's Graeme Norton Show, copied to my pc and using VLC, has very stuttery sound problems.
It plays fine on my ET10K.
It appears to have been recorded with 6 audio channels...

I have AC3 downmix set to yes, shouldn't both recordings have the same audio properties?

I haven't found an option to make VLC work properly, but Audio/Audio Track/Disable followed by Audio/Audio Track/Track 1 makes it work ok!!

Window Media Player plays the file ok, but kodi and dream player on a fire tv have the same stuttering sound.
