Get a piece of junk old laptop or desktop off family, friends, the street, the ewaste pile at work or a local shop. Laptops with broken screens are perfect for this. Even old macs are fine, good use of them since its so expensive to replace their displays.

I go to sleep with the History of Philosophy: https://podcasts.apple.com/au/podcast/history-of-philosophy-without-any-gaps/id396903391.

Everyone has different things they want for going to sleep, and this might not be right for you. But for me this is perfect because:

• its just the right level of boring. If it were any more interesting id stay awake to listen, if it were any more boring I’d turn it off.
• its not multiple people talking, because my brain thinks it needs to stay awake to be part of the conversation.
• i cant do video, needs to be audio.
• his voice is reasonably relaxing.

I seriously can barely get through 1 or 1 episodes before going to sleep. Another similar one is Dan Carlin’s Hardcore History.
