Hello Lucas D., I'm sorry to hear that you're having issues with your players hearing you. To rule out potential causes and provide the necessary information to the devs, please carefully work through Steps 1 through 8 of the Roll20 guide to Audio Visual Troubleshooting : Step 1: Make sure you’re using the most recent version of either Chrome or Firefox Please check if these issues persist when using both Chrome and Firefox. Step 2: Give Roll20 permission to use your microphone and camera Step 3: Make sure Video and Voice are turned on inside Roll20 Step 4: Clear your Web Browser’s Cache Step 5: Make sure you have the right ports open Step 6: Check if your camera is working with WebRTC Step 7: Check that your camera is functioning Step 8: Do a bandwidth test If none of the above succeeds, please thoroughly work through Step 9 : Step 9: Solving Technical Issues Step 9.2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions. Step 9.4: Provide a bug report Please ensure that the Console Log is complete. If you have a macbook pro (or a macbook in general), try this: open a terminal and type "sudo killall VDCAssistant" to see if this solves the issue. Information can be found here in an Apple forum post . Thank you!
