As a mainly-for-fun project earlier this year, I bought a Raspberry Pi 4b with 4 GB of ram and loaded the Raspberry Pi OS, Java 8 for Linux, and Room EQ Wizard. It seemed to run ok, although I did not give it a thorough workout, because I quickly discovered that only the L and R mains outputs were accessible as REW output channels. Then I found a post (somewhere, I can’t find it again now) where this was addressed by John M. John said that the Java libraries for Linux were the issue, that they did not make all of the HDMI output channels individually addressable in a way that he needed for REW to be able to work with them.

I recently got thinking about loading a Raspberry Pi with the ARM version of Windows 10, plus Java 8, plus Room EQ Wizard, and wondering if that combination might work.

Here are my questions, mainly addressed to John M., but I welcome input from anyone who has tried this out.

  1. For the Raspberry Pi OS, I assume the same limitation exists in the Java libraries preventing addressing all of the HDMI output channels individually by REW. Is that the case?
  2. Is there a version of Java 8 that works with Windows 10 ARM version providing the audio libraries needed for REW to work?
  3. Are there any other known issues that would prevent Room EQ Wizard from working with Windows 10 on an ARM processor?

Thanks for your help.

Only the Windows Java runtime lacks support for multichannel audio, Linux and macOS are fine. I don't know the answers to your questions, perhaps someone else will comment.

Thanks, John, it was many months ago that I ran across the post that I referenced, and my memory of it is hazy. I must have misinterpreted it.

So, to your knowledge, should one be able to individually address all 8 HDMI channels as outputs in REW on a linux system? I better try it again.
