Asus Tinkerboard S & the new Hifiberry DAC2 HD -> Failed to open “alsa”

Volumio Information

Volumio Version: Volumio 2 (2.861)
Hardware: Asus Tinkerboard S
DAC: Hifiberry DAC2 HD

That ist my first post at the volumio forum.

I hope someone can help me.

When i try to enable IS2 and chose my DAC from the list and restart i get a error message (Failed to open “alsa” [alsa]; Failed to open ALSA device “hw:2,0”: No such file or directory" when i do play a song but when i select the DAC from the output device list it plays audio but no sound is comming out of the dac.

could someone point in the right direction to fix this problem

Thanks

Asus has put a lot of effort in making various DAC devices, known from the PI, work with Tinker S and their support to the community has been excellent.
But, this does not mean that ALL working DAC devices on PI also work on Tinker S. I guess Hifiberry DAC2 is new and not one of them that does work without a kernel update.

Edit A kernel update is needed to integrate overlay “hifiberry-dacplushd”, but Asus has not done any new overlays for over 2 years.
