We attempted a stream of a high school event this evening and had no success. We were trying to connect to our YouTube channel, and it kept saying that the audio I/O failed. It presented with this log. It looks like for whatever reason it doesn't like the audio settings we had for the event, but they're no different than any we've had in the past.

Guidance and diagnosis are appreciated!
