We just participated in our first LRT event this weekend. While most things went as smoothly as could be expected, we had a terrible sound problem with the remote.robotevents.com site. Any time we unmuted for more than a few seconds, we got a lot of echo/feedback, to the point that it was nearly unusable. This happened even when we added external speakers to the PC and placed them as far as possible from the PC’s internal mic. It seemed a lot of the other teams had similar issues, so most were communicating with the ref via visible gestures (thumbs up, nodding, pointing, etc.).
Does anyone else have this problem? Any advice for avoiding it in future events?
