Here’s a thought. I recently added the last line to /boot/config.txt - code: < dtoverlay=gpio-shutdown > to allow a soft shutdown of the raspberrypi4 with a trigger on pin 5 (GPIO 3) from the vehicle ignition switch. Is it possible that interferes with the AudioInjector Zero’s connection to the rpi via gpio?
I have uninstalled pulseaudio and uninstalled alsa-common (and others alsa-related) and reinstalled each alternately with no change. I uninstalled pulseaudio and made sure all the proper settings were made in alsamixer, still no sound. It does, in fact, look like the pulseaudio issue, except that without pulseaudio I still get no output.
A related issue is that OpenAuto Pro requires pulseaudio. Without it, I get no audio controls (volume in particular) in OAP. OAP made that change when Raspberrypi.org <http://raspberrypi.org/> went to pulseaudio. If the AI zero will not function with pulseaudio, I may have to find another sound card for my OAP and move my AI zero to another project.

I recently re-installed the latest OAP version, starting from scratch, and updated everything, did the AudioInjector shell install and everything was working fine. I just did another update of raspbian - sudo apt update and sudo apt full-upgrade, this evening (03/19/21) and suddenly my soundcard is no longer showing up. Your response to the other email indicated an issue with Pulseaudio. I don?t believe this is the issue (but I may be wrong) because it was working just fine a few days ago (Raspberrypi.org <http://raspberrypi.org/> went to pulseaudio by default some time ago). Now, after the recent update my card doesn?t show up. It is installed correctly. I re-ran the setup script this evening when I discovered my AIZ wasn?t outputting. I can see that my iphone is connected via bluetooth to the rpi and that it is registering sound input, but there is ?no output device?.
