An issue which (I think) has been introduced in one of the recent versions - when streaming audio via Bluetooth, the video freezes after couple of seconds. In fact, it starts “buffering”, but just hangs there seemingly forever. I’m using an up to date OSMC (March update) on RPI3, with a Bluetooth dongle.
Below is a log showing two attempts at playing a video file - the first time (no Bluetooth), everything goes smoothly, but once Bluetooth is connected, playing the same video causes OSMC to buffer “forever”.
Let me know if more info is necessary?
