I rather doubt that I'll figure this out without access to hardware for local testing and tinkering. If you spot a hifi-shield card or even a complete C2 with one included for sale somewhere let me know.
I did reach out to HK but got their standard-ish "oh this is no longer sold.." response which basically means they no longer care for support (outside of their legacy kernels) and as usual support is entirely up to the community.
Hi chewitt,
I created an account just to ask you if you are still interested in a HiFi-Shield2 card?
I have an Odroid C2 at home that I was able to revive with the help of LibreELEC. As I am now using a SMSL AO-300 through USB, I have a spare HiFi-Shield2 card that you might use to add support in LE.
Would you be interested?
Thank you again for all your hard work and saving electronics from e-waste!
