Hi all!
I'm not getting any sound out of my octo, not even when running speaker-test
-c 8 -t sine -f 500.
Any pointers you can give me would be appreciated. Thanks in advance!

Hi all -
So after a little tinkering I managed to get sound out with the speaker
test command that I sent in my previous email. However, after recording and
playing a wav file, I hear nothing. Could the problem be on the
recording side, not the playback side? And if so, any recommendations for
how to fix it?
Thanks!

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 ?

Someone named Matt responded on a separate email, so I had some communications with him. Summary:
I got the AudioInjector Zero card working, but poorly. The sound card was not being recognized by Pulseaudio and did not show up as an option under Alsamixer. 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 tried CubicSDR and GQRX on the rpi and neither will work with the soundcard. I assume this is also a result of PulseAudio, which they seem to default to and which does not recognize the IAZ card at all. VLC doesn?t seem to have any problem at all connecting to the card and sound is good.
From what I?ve been reading on a couple forums, the HiFiBerry DACs are having a similar problem.
It appears a new driver for the IAZ for PulseAudio is needed. Will this be coming any time soon?

The card is on the system.
aplay -l should list hw:0
Try getting the mixer up :
alsamixer -D hw:0

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 just read another very recent thread (02/21/21?) that appears to have the same issue I have.
I have a AI zero installed on a raspberrypi4B with OpenAuto Pro installed on Raspbian. 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?.
I am familiar with linux, but not adept. where should I start to debug? Alsamixer indicates "there are no controls for this device? and no sound device shows under ?F6?.

Hi Tony,
This certainly sounds like the pulseaudio problem. What does the
following command output ?
cat /proc/asound/cards

I forgot to mention, I haven't worked out yet what it is in pulseaudio
and its configuration for Raspbian which is creating these problems. I
assume that pulseaudio is setup for a specific hardware expectation.

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 just read another very recent thread (02/21/21?) that appears to
have the same issue I have.
I have a AI zero installed on a raspberrypi4B with OpenAuto Pro
installed on Raspbian. 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?.
I am familiar with linux, but not adept. where should I start to
debug? Alsamixer indicates "there are no controls for this device?
and no sound device shows under ?F6?.

Hi Tony,
This certainly sounds like the pulseaudio problem. What does the
following command output ?
cat /proc/asound/cards
