I find it nearly impossible to retain any information from audio sources, be they podcasts or audiobooks. Lectures are usually fine, unless they're just someone standing up and talking. Presentations with suitable diagrams, animations, illustrations, or photographs are OK, but far, far, far away the best medium for me is the written word supported by appropriate diagrams. For me, podcasts and audiobooks are a (near) complete waste of time.
