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