I want to #RTFM, but for that I need a real #manual, not a #quickstartguide.
Found the issue with my #PS5 and receiver: Boot into safe mode, force #HDCP from auto to 1.4, which is what my 2010 Yamaha AV rec supports. But how did I find that? 1) Appending "reddit" to my searches, because without it every result in any search engine is the same stupid quick start guide or how to upgrade your old PS4 games. 2) searching youtube with #freetube because the website search is worse than Google.
