ROCK on Raspberry Pi4?

Considering how powerful the RPi 4 is, would it not be possible to run a modified ROCK on it, or some other form of Roon core? Sure, some things like up-sampling to DSD512 or very advanced convolution filters would not work, but for more normal use-cases the RPi should be powerful enough.

Combine this with a RPi DAC HAT and a RPi LCD and you get a very neat stand-alone solution. Or a HAT like HiFiBerry Digi+ Pro to get a good SPDIF out to your DAC.

You mean the equivalent of a Squeezebox Touch? Yes, that would be nice if that were finally possible.

I strongly suspect that you’d need to use an M.2 SSD drive in an add-on HAT instead of the micro-SD card for starters. Then of course Roon Labs would need to make ROCK available in a version suitable for the RPi. I’m not holding my breath - and I would rather their development efforts be spent elsewhere…

It has 2 USB3 connections, so a USB disk should also work (at least for storage and meta-data). Which drive thats used for booting should not matter much for Roon core performance.

The most common complaint about Roon is that a computer is needed to run it, and this would provide a cheaper alternative to a regular computer.

Roon’s database needs SSD for Core performance (unless you’ve only got a small library). Internal SSD transfer speeds are, I believe, over twice as fast (on X64 architectures) as what can be achieved using SSD attached via USB 3.0. So I suspect an RPi4 is still only good for small libraries. And it will still require Roon Labs to provide a version of Roon Server for arm…

As advanced as the Pi4 is for its architecture, it is nowhere close to having the power of a Core i3, the recommended minimum. Roon needs fast base core(s) rather than more cores for most operations.

Here we go again…not going to be workable…it’s been touted before.

currently, even roonbridge does not work properly on RPi 4B. I have opened tickets with both Roon and Raspberry Pi firmware groups.

Let’s hope a fix comes out soon.

@Shawn_Kernes
can you tell why it does not work as bridge? i thought that it did work with pi3. and i was waiting for the pi4 version hoping for a multichannel capability. as player, not as core…
