ALSA version for PatchboxOS 2022-05-17

Hi everyone,

Still continuing my setup preparation before receiving my pimidi. I was able to successfully to install patchbox os 2022-05-17 on a PI 3B+.

it seems that the version of ALSA is “quite” old because I was not able to build rawmidi.c for github (the symbol SND_RAWMIDI_READ_TSTAMP is missing) [*]. If I am right, stamping in raw read method appears in Oct 28, 2021 (around this date).

I don’t want to upgrade to the latest version of patchbox OS as there is an issue with booting on PI 3B+.

Any advise on how to proceed ? shall I stay to the current version of ALSA ? As I am discovering this library, it might be difficult for me to find the best support. in general manner, I am quite newbie with Linux

Thanks,

[*] FYI, testing it on Ubuntu 24.04 is OK.

What is the issue with Pi 3B+?

Go with 2024-04-04 or just the latest Raspberry Pi OS image.

In the release notes 2024-04-04, it is mentioned a crash during the boot (due to the USB possibly).

I will try, thanks

It’s about the realtime kernel build which has to be switched to from within the Patchbox CLI. It works with 3B+ using default settings just fine with the stock kernel.

Thanks for the feedback

I have noticed that it was for the rt kernel.

I might need this. I want to dev my own MIDI sequencer
