BT issues with F5122 on 4.x

It seems since the upgrade, BT playback has a wired chracteristic, that sometimes it loses the plt completely and it sounds like different streams within the same song are playing simultaneously. It doesn’t happen every song, maybe 1 in 10 it suddenly goes off the rails.

I haven’t tried to isolate whether it happens on every BT device or every media player yet, but I am certain that it is not the rips themselves

Has anyone experienced this?
