RuneAudio 0.6-beta for most Raspberry Pi models

[janui]

Current build version: janui-20231210-6

Way back in 2018 we published RuneAudio 0.5b. In the meantime, lots has happened, Rern has developed his own version, and we continued plugging away at the Classic RuneAudio version. The 0.6b version was nearly published several times, but we were repeatedly caught out by some sort of technical change which caused delays. We now have something stable which we would like to share with you.

RuneAudio 0.6b will run on all Raspberry Pi hardware types, except the new Pi 5B. There are now two versions:
• A RPiOS-bullseye 32-bit version which will run on all Raspberry Pi hardware, except the Pi 5B.
• An ARCH-aarch64 64-bit version which will run on the Pi 3A+, 3B+, 4B & Zero 2W hardware.

There are some differences between the images, but they are functionally the same. Some features are disabled when the RPiOS version is used on the slower single processor models.

We are still making small improvements to the images. After setting up your installation you can use the git pull function in the /dev UI to upgrade to the latest version. For instructions see here: http://www.runeaudio.com/documentation/ ... rd-updates. The current build version is mentioned in the first line of this post. Your current version van be seen in the Debug UI, Build version: janui-20231210-x.

Here is the changelog for 0.5b > 0.6b: https://raw.githubusercontent.com/gearh ... b_0.6b.txt
Here is the issue list concerning 0.6b: https://raw.githubusercontent.com/gearh ... t_0.6b.txt

Messages concerning bugs, issues, problems, and all other comments are all welcome. Please use the forum.

We are currently testing a version for the Raspberry Pi 5B, this will be available early in the new year.

Have fun,
janui & Gearhead

The images are designed to fit on a 8Gb Micro-SD card.
The first boot of the image takes quite a while, it can take 5 minutes on the single processor hardware, have patience.

Exciting!

Just tried some audio files (primarily FLAC and DFF), but all bitrates except for 16/44.1 play with hick-ups/stutter at the start.
Tried raising the "audio buffer size" to 16384 to no avail.

Great!

Thanks janui and Gearhead for your effort!

The hickup/dropouts at the beginning of tracks are, according to me, related to (flac) files with a bitdepth of 24.

Hi janui,

I also tried your suggestion to test editing the file ‘etc/mpd.conf’. I only tested the option “*:16:* *:24:*”. No success.

- Doubling the ‘Audio Buffer Size’, brings no improvement.
- I’m certain that MPD is not updating, when the dropouts occur.
- I checked the SHA256 ckecksums.
- Up to now I didn’t try an another Micro-SD card.
- I do not use a Wi-Fi connection.
- Via an USB-port a HDD is directly connected as source for the music files.
- The debug info give only zero for the counters ‘errors’, ‘dropped’ and ‘missed’.
- I’m able to produce the log via Putty, but lack the (elementary) skills to copy/export it. By the way I see several ‘warnings’.
- I use at moment a Pi2 Model B rev 1.1. I’m aware this is not a ‘fast’ one, but worked fine with RuneAudio 0.5b. I could try a Pi3, but as Beelzebassie also encounters a problem with a DigiOne, I don’t think that a higher clocked Pi is the solution.
- The dropouts occur after about 1 sec, then at about 3 sec, and then approximately after 10 sec.

Hello.

Recently I swapped, because of the dropout problem, several times between version 0.5b and the new version 0.6b. It could be imagination, but I noticed that the version 0.6b sounds better. The music is more detailed and has a nice and more balanced sound. The music is more at ease. Up to now I only used the default Sound Signature. I didn’t expect an improvement in sound quality, so it surprised me. Is this because of a better jitter performance with the new kernel? I use RuneAudio with a Pi2 and Allo DigiOne. The Allo DigiOne is renowned for its low jitter spdif output. So what could be the explanation of this soundwise difference between 0.5b en 0.6b?

@janui or others. Please enlighten how the Sound Signature tweaks may affect the sound.
What is the experience of other RuneAudio users with RuneAudio 0.6b?
