I tried dietpi but it looks like it doesn't support the onboard audio ("This option is not available for the Pine A64..."). Thinking I should have went with a raspberry pi now... The Pine64 is an amazing board but might not be the right one for me. This is the 3rd or 4th OS I've tried on the Pine64, haven't been able to get headphone audio out of any of them.
I also tried the "Longsleep's Xenial Ubuntu Image" you mentioned, but I don't think the HDMI works for me. I get output for a while, then it goes back and never comes back.
