I have Tinker Board with latest Volumio (VERSION: 2.349, RELEASE DATE: 25-12-2017) and several I2S boards and confirm the result as following:
IQAUDIO – PI-DIGIAMP+: working out of box
IQAUDIO PI DAC+: not working, not seeing via alsamixer
502DAC as Hifi Berry Plus: not working, even seeing via alsamixer but no sound
I have an hifiberry digi+, what do you mean it’s for Pi1? I used it with Pi2B and 3B.
It’s currently not in use, but since the Allo isn’t supported on the TB (yet) I will try the TB / digi+ combination later this week.
It’s so sad…
This could be a kind of “rescue hero” for all user who wants to use USBridge further which is one of the best USB audio output HAT…
Who will be able to create the required drivers/overlays? (the Asus?) Is it possible to porting that from the existing Pi driver?
wait a minute, you mean the original one from the Sparky board?
The original one is not PI compatible, so you can really forget about it.
I was confused about the PI, that is a very different solution (Usbridge Signature with a PI compute module)
Yes, you’re right - I mixed up these too Sorry.
The existing USBridge driver is for Allo Sparky (not PI)
The Sparky GPIO isn’t compatible with the Pi or Tinker Board
