Still working here, nice quality indeed.
I'd imagine it'll be delayed at least 10 seconds or so, not really possible to webcast video any closer to live than that, by the time it's been encoded at their end and buffered at your end.
HDMI transfers both video and sound, so if you're not getting sound out the telly, then either you've got a dud HDMI cable, or either your telly or your laptop is fibbing about supporting HDMI
Never that keen on taking strikers on loan for first half of season anyway. If they're any good and bang in a few goals, you're waving them off home again in January just as the most important part of the season is approaching, usually to be replaced by somebody who presumably wasn't quite as good in the first place.
