Hi Bruno, sorry you're having trouble with audio volume using Roll20. Could it be the Master music volume slider of Roll20? This is located under the settings/Gear icon above the chat. Wiki docs: <a href="https://wiki.roll20.net/My_Settings#Master_Music_V" rel="nofollow">https://wiki.roll20.net/My_Settings#Master_Music_V</a>... If that's not it... Please doublecheck and follow all of the instructions on the Audio Visual Troubleshooting wiki page, to make sure those bits are in order. If the wiki does not solve your problem, head back over to this thread and let us know any additional details to help us further figure out your issue. Are you able to hear sound effects through roll20? Are you using the voice feature, and is everyone's voice quiet?
