Merging supports just x64 architecture. RAVENNA driver is mostly user space binary only component for x64 driver. With kernel space shim. So at the moment, it is not possible to support that on ARM platforms, even if one would want to. HQPlayer, first Embedded for a long time and now also Desktop has been supported on RPi4 (HQPlayer OS on Holo Red, etc). And I'm planning to support RPi5 with HQPlayer OS as well. But RAVENNA is limited by the driver implementation and tricky hardware requirements. USB/I2S/NAA of course works fine. blueninjasix and The Computer Audiophile 1 1 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment
Miska Posted February 26 Share Posted February 26 I don't know, I haven't used RAVENNA in a while. I gave up on the Linux driver, which didn't seem to like realtime kernel and few other things. Their newer driver worked fine on Windows and macOS. I don't have any RAVENNA hardware anymore. Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

I'm using both the Debian with Desktop, and Ubuntu without desktop on my Pi. I don't think rt kernel is necessary, but I ran into one issue and wanted to try it. I see people have rt working on Pi 4, but I haven't found anything for Pi 5. Most ARM kernels are not safe with RT. This is because the of the flaky/bad programming practices in various drivers. So you may experience lockups and other strange behaviour with RT kernels on ARM. Plus the extra overhead involved with RT kernels may make the overall performance rather mediocre (drivers become threaded kernel processes, and lack of HyperThreading kind of functionality costs). This is the trade-off / balancing you need to consider between bandwidth/throughput driven (server) kernel where latency is bad, or latency driven (desktop) kernel where bandwidth/thoughtput is bad. yamamoto2002, The Computer Audiophile, blueninjasix and 1 other 1 1 2 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment
Miska Posted March 29 Share Posted March 29 I'm personally using the official RPi5 PSU. Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment
