Real problems with the BBC feed of the Masters Snooker this afternoon - it started late with no sound, then ambient sound with no commentary. A few apology captions later (including accidentally putting up the template for when coverage switches between tables) sound and graphics went entirely. It looks like they lashed together some coverage from just the static camera for the full table and only the table mic before resorting to the Temporary Fault card and a total reboot in the gallery by the looks of things.
As I write it's still OK ish, but sound levels are all over the place.
EDIT: Sound has gone again as soon as the interval ended, clearly something is very wrong with the feed.
