Common Mistakes to Avoid

1. Incorrect Audio Output Device Selection

Reason: Your computer might be sending audio to headphones or speakers instead of the presentation's audio output (e.g., a projector or streaming software).
Solution: Select the correct audio output device in your computer's sound settings before starting your presentation.

2. Muted Microphone or Speakers

Reason: Accidentally muting your microphone or speakers during the presentation will prevent others from hearing the audio.
Solution: Double-check that your microphone and speakers (or the presentation's audio output) are unmuted.

3. Poor Audio Quality Due to Software Conflicts or Low Bandwidth

Reason: Conflicting audio software or insufficient internet bandwidth can result in choppy or distorted sound during streaming presentations.
Solution: Close unnecessary applications, use a wired connection if possible, and ensure that the software used for sharing the audio is compatible with your computer and network.

FAQs

My computer audio isn't playing through the presentation software. What should I check?
Ensure your computer's audio output is set to the correct device (usually your speakers or projector). Also, verify that the 'Share Computer Sound' or equivalent option is enabled within your presentation software (Zoom, Teams, etc.) Check for any volume controls within the presentation software itself, too, as these might be muted.
I'm experiencing audio lag or echo. How can I fix this?
Audio lag can be caused by network issues or processing limitations. Try closing unnecessary applications to free up system resources. If using a wireless connection, switch to a wired connection for better stability. Adjusting the audio settings in your presentation software (e.g., lowering the audio quality) might also help reduce lag.
