Hello
I’ve deployed successfully Balenasound on Orange PI Zero LTS
The thing is audio service doesn’t detect any sound card
09.05.22 17:00:51 (+0200) audio — Audio —

Any solution ? It’s working fine on Raspberry PI 4, but since the cost of this one is over expensive, Orange Zero is a great alternative
Thanks for your help

Hi,
I found a previous forum post where you say that you solved this using Volumio: No sound on Orange Pi Zero - #2 by beber666
Could you expand on how you used Volumio, and why that didn’t work here?
Thanks,
Christina

Hello
Thank you for your reply 
That’s sad to say, buy Volumio works out of the box on my Orange PI Zero 1
With Balena Sound, it’s almost perfect, except I don’t have sound…
Do you have an idea to fix this issue ? Because I really prefer to use Balena Sound

@beber666,
Can you share which version of balenaOS you’re testing in both instances? I’m wondering if there are any updates to meta-balena that you might be seeing in Raspberry Pi images (which we update frequently) and the Orange Pi Zero images (which we update less frequently)?
Our plan is to automate testing over time so that we are better able to keep up with updates across our device-types, but today it is a manual process, so we update mostly upon request for the less common device-types, of which the Orange Pi is one.
Anyway, let me know about your OS versions and then we can look into updates between them in meta-balena to see if there are updates that might have resolved audio issues for RPi that you’re not seeing in Orange Pi. Thanks!

Thank you for your support.
Here is the informations about the version I used [balenaOS 2.53.9+rev1]
Diagnostic file if needed PrivateBin (you need to wait a bit to let it displaying)

Hi, sorry! A colleague has sent a reply though our internal support system, but for some reason it didn’t get replicated to the forum as it should. I am copying his response below:
Hi, the default sound output for Orange Pi is HDMI (http://www.orangepi.org/wiki/2015-01-19/98.html). Do you have a way of testing whether sound would come out of it?

Thank yo for your reply
There is no HDMI output on the Orange PI Zero
With the hat, it bring the Jack Output, and in all cases we’ve got also the USB output
I guess that’s the issue !

Hi
From the diagnostic logs it looks like you’re running a GeneralPlus USB Audio Device like this one GeneralPlus | USB Audio Cards with a Raspberry Pi | Adafruit Learning System.
I don’t see that as directly supported, but you could try using the USB device output. Have you checked Audio interfaces - Home ? You may need to set up the device ( see Customization - Home and audio/README.md at master · balenablocks/audio · GitHub )

Hello
I confirm that the USB Audio is not working on this device.
But the exact same device works with raspberry PI with BalenaSound
I’m pretty sure it’s not the issue

I am having this same issue. Please is there a way to fix it??? I just dropped like $60 on 2 orange pi zeros and don’t want to have 2 paper weights…
On my side for the moment I’m using Volumio , there is community edition that is working great with Orange Pi Zero
I don’t understand why Balena doens’t support it, since Raspberry it simply over expensive for the moment
Hello,
From what you describe it looks like this might be a balenaos or balenasound issue.
We don’t have the bandwidth to investigate further at the moment, but this is a open-source project and we welcome contributions 
You should check the logs of the host kernel ( dmesg ) to see if there’s anything odd happening when plugging the usb sound card.
Hi
From the previous messages, it looks like the device is listed as a USB device but not as a sound card (snd-usb-audio).
In order to pinpoint the difference, it would be useful if you could plug the device on the raspberry pi ( where you mention it is recognized as a sound card ) and share the diagnostics file. That way we can compare both devices.
Thanks, Ramiro
Hi, I’m having the same issue. In my case I bought 3 Orange Pi Zero’s to create a multiroom setup in my home
I got a volumio image that I’ve configured if you need multi room, I’m using it, waiting for balena support it
Thank you for your reply, I’ve tried it, but since the Volumio build that I’ve found it’s for Orange Pi Pc, it doesn’t have Wifi, and this is not useful for me.
Best regards
