Hi,

I switched from raspbian to Leap 15.3 for my Raspberry Pi 3. But I wonder if there is a way to install the official Raspberry kernel, as it looks like some hats are not supported with the kernel provided by openSUSE. In my case the HiFiBerry (hifiberry dac+ pro).

Or is do you know if there is a different way to get the snd_rpi_hifiberry_dacplus kernel module (? Thank you in advance :)

It is common that code gets cleaned up before it is accepted upstream. The "hifiberry dac+ pro" is, AFAICS only a PCB around the Burr-Brown DAC PCM5122 (https://www.ti.com/product/PCM5122), which is supported in mainline by the snd_soc_pcm512x module. All you probably need is a device tree overlay that describes how it is wired up. That DT overlay in turn will then carry the "hifiberry dac+ pro" name or similar. See Documentation/devicetree/bindings/sound/pcm512x.txt in the kernel source for the syntax and upstream "compatible" strings. Torsten
