How Do You Test Audio Before Presenting in Google Slides?

While learning How to Add Audio to Google Slides , I realized that adding the audio is only part of the process. Presenters also need to think about playback quality, device compatibility, internet access, volume levels, and whether everything works smoothly before presenting. These small details can have a big impact on the audience's experience. I'm interested in hearing different perspectives on this topic. How do you test and prepare audio in Google Slides before a presentation, and what steps do you recommend to avoid technical issues?
