Do you happen to have a good reference on using the Pi3 for audio? I spent a lot of Saturday trying to make mine do some stuff, and while a lot of the technical snafus were the usual sort, I did end up burning a lot of time googling around until I finally found someone who suggested turning off CPU performance scaling. Which was a forehead slap moment for me after that, but, still, it'd be nice if there was somewhere I could go that had that stuff more laid out.

(As implied, I've googled already. A lot.)

(The Pi3 seems to have more than enough CPU power for it to do what I want but I was having trouble just routing audio in a USB mic straight out to the speakers without dropouts and failures two or three times a second, even though the CPU is barely at 10%. I think turning off the scaling seemed to fix that, though I ran out of time just as I tried that to be sure.)

You may want to check out some of the posts at https://autostatic.com/ and the forums for zynthian https://discourse.zynthian.org/ . If memory serves both sites focused on some of the version 2 revisions of the Pi, but they may also help with your board as well.

Thank you. Using those with site: in Google has produced some interesting hints.
