This is a random question but is it obvious, one way or another, if there were actual technical problems with this singer’s mic?

The Buffalo Sabres always play the Canadian anthem at home games, the fans can be counted on to sing it (and we love our Canadian neighbors so the chance of us booing is pretty slim). I’m wondering if the NHL decided to cut the singers mic and show that off, to counteract Anaheim fans booing the Canadian national anthem earlier this week.
