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

Sat Mar 27 18:54:44 UTC 2021

Hi Tony,

I think you are under the impression that I have an official relationship with Audio Injector folks. I don't. I was simply attempting to lend a hand with trouble shooting.

My application works fine on the RPi 4B running the latest Raspberry O.S. (with PulseAudio). My application uses the services of PortAudio which by passes the PulseAudio stuff and talks directly to ALSA. I don't need an external volume control as the application manages volume itself.

Let me dare to say, that if other applications work fine with the current version of Raspberry O.S. (my application, VLC, etc) then the ball is in OAP's court. The problem is definitely not a driver issue.

73,
Ron / W4MMP

The AIZ still works fine under raspbian, when I install Alsa alongside PulseAudio, but when OAP is running the sound level is lower and has a lot of audio interference. As soon as I exit OAP, the sound is fine again. Without PulseAudio, OAP has no volume controls and there is no sound at all. I wish I were better at troubleshooting software, but my knowledge of coding is pretty shallow.

I initially had the card installed under Raspbian/OAP on a raspberrypi 3B, then moved to a rpi4B last year. It was working fine. The card’s hardware configuration was exactly what I needed. The mic input on the card made it possible for me to use it for hands-free telephony under OAP. It was perfect! I was hoping this was just a driver issue and that it would be resolved soon.

Most of the folks using OAP seem to be using USB dongles for their sound, but the AIZ is a much better option in my opinion. Having the card mounted via a 40-pin header and solid stand-offs is much more robust than a USB connection on a dongle, when you’re talking about installation in a vehicle. I am hoping there is a software/driver solution for this issue that allows me to keep the AIZ card under OAP. Since Raspberrypi.org went to PulseAudio, I doubt OAP will do anything differently, so I think the ball is in your court.

Without PulseAudio, there is no sound and no volume control. I really like the AudioInjector Zero sound card, but I guess it?s not going to work for my usage under OAP as part of my vehicle?s head unit. I?ll find another use for it.
