OPPO HA-2 native support

Good news. I don’t know if it’s attributable to (my) user error or recent update to macOS 10.13.5, but my Oppo HA-2 and bcm2835 ALSA IEC958/HDMI devices are working well. Thanks!

The ALSA device isn’t providing “UltraHQ” quality over HDMI as DietPi implies, but that’s probably to be expected given its Linux kernel limitations. I think the so-called “UltraHQ” refers only to reimplementation of the original onboard 3.5" analog jack PWM-based 11-bit audio @48kHz as 7-bit 2nd-order Sigma-Delta modulated at 781.25kHz, as described here:

Appreciation to @john and @support. Roon is working great for me!

Hello @Psychoakustik,

Glad to hear it. This one was a bit of a head scratcher for sure. Enjoy your music and feel free to reach out to us if you run into any more issues!
