Jamulus crashes on macOS

[harmonk]

Jamulus [3.11] has been crashing for about a week now. I open it, it runs for seconds, then blink, gone.
I am on a Mac Macbook Pro, Sequoia 15.2 - updated recently, could be related but find no other reports of problems. And i believe Jamulus ran fine for a short time before this problem began.
I have reinstalled Jamulus several times, deleting all related files each time. Restarted the computer.
I use J with Zoom often, thought that might be an issue but J crashes with no other apps open.
Anybody else? Any ideas?

Jamulus requires that the device in use support 48KHz bitrate. Try this:

1. Run Applications > Utilities > Audio MIDI Setup
2. If the Audio Devices window is not visible, show it with Window > Show MIDI Devices
3. On the left side, select each device and confirm that both Input and Output format = 48000 Hz

#3 is particularly important for your default Input and Output devices (usually Mac Internal Microphone and Mac External Speakers, but can vary by device).

Then launch Jamulus. I'm just guessing, but maybe it's defaulting to a device that's not set to 48KHz and that's causing a crash.

A quick vid of how the windows look.

Hmm. This looks like the window doesn't get closed correctly by Qt.

My graphics seem to be fine. No other issues, things look fine, we watch videos and play games and so on.
I downloaded that legacy version [though doesn't it have the same version number as the latest Jamulus version?] and installed. Same reult. It ran for about two minutes before it crashed the first time, then crashed immediately from then on.

With this legacy version, at least i don't have the shadow window issue anymore.

With this legacy version, at least i don't have the shadow window issue anymore

Which means that it could be a Qt related bug.

I don't have an (apple silicon) Mac on 15.2 unfortunately. Currently, it seems as if it only occurs on your hardware - which I find odd.
@chrisrimple You can't reproduce this problem either?

As soon as Jamulus crashes, does an error message from macOS show up? It would be good to see the crash logs.

Otherwise, open macOS console and look for any errors from Jamulus reported there.

[harmonk]

I must admit i am not sure where to find crash logs. I have made at two reports to Apple about this, and so i look in Console and see on the left 'Crash Reports', but there is nothing relevant there. Where must i look?

[harmonk]

I searched in Console for Jamulus, nothing found.

Did you use https://support.apple.com/en-us/guide/console/welcome/mac

I would leave it open and view it in real time until a crash happens again.

Some questions:

• Which audio hardware did you try? Internal devices + Focusrite?
• What is the exact model + year of your Mac? Is it Intel or Apple silicon?
• Did you remove zoom already and tried if there's a crash? Zoom might run in the background. Are there any other apps which access your audio gear?
• Does it only occur with the latest Jamulus version?
• Did you try opening Jamulus via the terminal already? Do you see any crash in the terminal?

[harmonk]

Audio hardware: with and without Focusrite. It doesn't seem to matter what hardware is present, or not. Mainly i have been testing with nothing attached.
Macbook Pro 14in 2021, Apple M1 Max chip, Sequoia 15.2.
Activity Monitor says that Zoom is not running at all. I will try removing it completely and report back. I used Jamkazam before with the same setup, but that was years ago. Logic Pro too, sometimes i hook it up with the FocusRite. But i have been doing these things for years without an issue.
I posted about about downloading a legacy version [(https://github.com/jamulussoftware/jamulus/releases/download/r3_11_0/jamulus_3.11.0_mac_legacy.dmg) ] and tried it. Same result.
Opening Jamulus via Terminal? Tried it just now, opening that legacy version. Jamulus has stubbornly refused to crash ;) monitoring now.

[harmonk]

And it crashed again, after being on for maybe 30 minutes. With Zoom also on.
Weird coincidence: It crashed twice finally. Both times, i opened Signal and sent a message. Boom, Jamulus crashed. Twice.
This, for all openness. Who knows, could be relevant.

Did you rule out a hardware issue: https://support.apple.com/en-us/102550?

[chrisrimple]

I'm not experiencing similar problems with 3.11 on MacOS Sequoia 15.1.1, but I have not yet upgraded to 15.2, so can't say yet if that's the issue. 2021 MacBook Pro M1 Max.

Another suggestion: does the Mac artifact from https://github.com/jamulussoftware/jamulus/actions/runs/12525153233 work? That’s built with the latest Qt version.
