Final answer:
If a user sees their speakers listed as "Output 1", "Output 2", etc. and are using Microsoft Edge to join a video visit, they should manually select "Output 1" as their speaker.
Step-by-step explanation:
If a user sees their speakers listed as "Output 1", "Output 2", etc. and are using Microsoft Edge to join a video visit, they should manually select "Output 1" as their speaker. This is because the listed speakers represent different audio output options available on the user's device, and they need to choose the appropriate one for their video visit. By selecting the correct speaker, the user will ensure that the audio from the video visit is played through the desired audio output.
