Read More…The Orange Pi Home Media Center is a compact and neatly designed hardware project that combines the power of the Orange Pi One board and the Hi-Fi audio capabilities of the TI’s PCM5100 32-bit DAC. This versatile media center provides a customizable and fully open-source hardware platform for home entertainment.
With a minimalistic but functional design inspired by commercial audio gear, it offers a seamless user experience. It aimed to support Volumio, Mopidy, or any custom firmware you may come up with.
I did a few audio projects in the past, some using ESP32, some using popular Raspberry Pi devices. Each has its pros and cons, and with each iteration, I'm trying to focus on the details that were working best for me, while using them myself on a daily basis.
What is special about the Orange Pi is the amount of hardware power that you get for your buck. Surely, the ecosystem is not as rich as Raspberry Pi, and the community is not so vast. But Armbian is still a Debian-based system and most of the things you'd want to run, just work!
Orange Pi HiFi is a first-in-line product that uses the legendary PCM5100 series DAC with supreme audio quality. It exposes line-level output that you can plug into a stereo amplifier. Spend as much as you need on the external amp to deliver the sound you like (personally I prefer late 80's audio gear).

Being a Debian-based Orange Pi Media Center is a vast space for experimentation. First things first, for any OS you need to configure DAC. The below instruction is based on Armbian experience, that supports the current kernel (thus already having DAC kernel modules).
The linked Github repository provides detailed instructions on how to configure and test DAC in a few bash commands.
Ansible is an automation suite that allows you to configure systems remotely using redistributable configurations called playbooks.
A few playbooks were created to allow 2-clicks deployment for Hi-Fi Orange Pi. The same can be done manually by pulling necessary packages from the vast Debian software store.

Most of the packages are sent the next business day in the morning CET time. Delivery time varies wildly, but typically it is 1-2 weeks within EU and 3-4 weeks outside EU due to delays in customs. If the package does not show up after 8 weeks, please reach out for a replacement or refund.
Currently, Poczta Polska does not ship to Israel, and a few more countries due to a lack of airline operations. As soon as they will lift the restrictions, I'll restore shipments.
