Hello, does the Libre Computer support the JustBoom Raspberry Pi Hats? I have the JustBoom Digi and I need to replace the old Raspberry Pi.
I run LibreElec and the audio output device for the JustBoom digi is:
Alsa Default (snd_rpi_hifiberry_digi Hifi wm8804-spdif-0)
JustBoom website seems out of service or closed.
Short answer is no. Long answer is needs software work depending on whether the HAT is based on PCM or I2S.
One more question; does the Libre Computer support Hifiberry DAC? It is based on PCM_CLK. Libre Computer also supports PCM_CLK on GPIO 18
HiFiBerry DAC+ Light and Zero use these GPIO pins:
GPIOs 18 PCM audio, 19, 20, 21 (Pins 12, 35, 38 and 40) are used for the sound interface.
See Libre Computer CC Boards GPIO Pinmux Compatibility Matrix
If you are doing custom wires to remap to the proper pins, all boards are supported.
You have to enable the PCM pinmux so that PCM is routed to those pins. Then you have to configure alsamixer to output on the right interface using the right audio format.
If you don’t know how, you can provide the base device tree from https://boot.libre.computer/ci/BOARD.dts and then ask Grok to make an overlay based on the specific pins you want to use and the pinmux on those pins.
