[AudioI] AudioInjector Zero no longer being recognized by raspberrypi 4 (Tony Henrie)

Thanks for the summary.
Is there a way to tell OAP which ALSA device to use and to bypass
pulseaudio ?
As I mentioned, The RPi Raspbian operating system isn't robust w.r.t.
Pulseaudio configuration. It is really something to discuss on their
forum and try to pressure them to improve it.
What are the contents of /home/pi/.asoundrc ?

I uninstalled PulseAudio and installed Alsa, but had no means of selecting the card, as alsamixer was no longer available. I reinstalled PulseAudio alongside Alsa, used the command specified below: aplay -D hw:0, to set the AIZ as default and got the card working again. However, under OpenAutoPro, there was a lot of interference, clicking, and low volume. Without Pulseaudio installed, there is no sound or volume control under OAP. With PulseAudio and Alsa installed, there is sound, but the quality is poor. If I exit OAP, the sound returns to normal, but the card doesn’t want to stay selected as the default. Every time I open alsamixer to make adjustments, I have to re-select the AIZ as default.

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 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.

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.
