Thank you for reaching out. The issue where the agent cannot hear the user when the user joins the room first could be related to how the audio tracks are being published or subscribed to in the room. One common issue is related to the "silence detected on local audio track" warning, which may occur if the microphone is not immediately active or if noise suppression features are in use. To assist you better, could you confirm the following details: • Are both the user and the agent successfully connected to the room? • Is the user's audio track being published correctly? • Are there any errors or warnings in the console logs for either the user or the agent? • Are you using any specific configurations or customizations in your setup? With this information, I can provide more targeted assistance or escalate the issue if necessary. Sources: Understanding "silence detected on local audio track" warning
