🔑 Important Device Information

Device IDs are security-scoped to specific origins/domains and browsers. They will appear different across domains and after clearing browser data for security reasons.
Speaker/Output selection requires granting microphone permissions first. Some browsers may require additional permissions.
For iframes, add allow="microphone *; camera *" to enable device access.
Browser compatibility: Firefox does not support audio output selection via sinkId. Safari added partial support in recent versions.
If device labels appear as "Default" or are missing, you need to grant media permissions before they'll become visible.
