Thanks again Dan,
I wasn't able to find a version from Nov 2019, but it looks like the version at the time was Buster. I reinstalled a 32bit version of Buster, then installed the overlay in the boot.txt, rebooted, enabled "Output Mixer HiFi" and tried to record .wav files using the various AudioInjector input devices.
I didn't have any luck getting audio in my recordings (I recorded onto a USB memory stick and then listened to the wav files on my laptop). To verify everything was working, I then installed my USB sound card and made a recording using it and was able to record from the input on it fine. So my command should have worked with the Audio Injector inputs.
** One thing that I noticed today was that I plugged a set of headphone into the phono jack while I had the RCA cables connected to the Audio In plugs and music playing over the RCA cable. I couldn't hear anything from the headphones. I'm not sure if that should happen, or if there is a setting somewhere to enable that. But I thought that I read somewhere that the input should play out of the phono plug.
Anyone have any other ideas?
Is there anything else that should be enabled? Sould the audio play from the headphone jack when there is audio in on the RCA plugs?
Thanks for any advice!

I've messed with so many settings with the "amixer" commands, and have verified that they took affect in "alsamixer".
