So does tone not enhance your learning experience in any way?

No. Tone is generally irrelevant, especially when I'm reading technical documentation. Having a manual page for a UNIX system function read to me isn't helpful. If it's read by a man, it'll bore me. If it's read by a woman, and she sounds attractive, I'll be thinking about disappointing her in bed instead of keeping my mind on the job.

Also listening is a lot less effort and can be done passively while for me reading requires a lot more of a conscious effort.

You might find that a point in favor of listening, but I find that conscious effort that reading entails improves retention. There's are reasons we have idioms like "in one ear, out the other", and I'm one of them. Besides, and as I mentioned before, audio and video are shit for reference. You can't grep audio and video and search by keywords. Audio and video generally don't come with indexes where keywords are connected to timestamps for easy access to relevant sections.
