Eqmac: Bug: Not Starting on macOS Big Sur

[chrisspiegl]

Disclaimer

I am aware that I am running a beta version of macOS, I just thought I'd report this so that it can be fixed ideally soon, but for the upcoming release at all. Especially since nowadays Apple is releasing public betas and those are available like 3 months before the public release and it would be too bad if eqMac would not work till Sept/Oct.

Describe the bug

When installing eqMac on macOS 11.0 Big Sur Beta 1 and 2, the program does work sometimes (weirdly enough) but then other times it does not start at all. The console prints the following when trying to launch via terminal:

$/Applications/eqMac.app/Contents/MacOS/eqMac

2020-07-08 10:17:41.901 eqMac[8116:132180] Sentry Started -- Version: 4.5.0
eqMac (Source/Application.swift:184) Setting up Audio Engine
Error: 2003332927 -> /Users/romanskisils/Programming/Bitgapp/eqmac/native/app/Source/Audio/Sources/System/Driver.swift:123
ERROR: SentryCrashMachineContext.c (232): void sentrycrashmc_resumeEnvironment(): thread_resume (0000d807): (os/kern) object terminated
[1]    8116 segmentation fault  /Applications/eqMac.app/Contents/MacOS/eqMac

Manually installing the driver anew, prints:

$ sudo /Applications/eqMac.app/Contents/Resources/install_driver.sh

Device not ready yet, waiting...
Device not ready yet, waiting...
Device not ready yet, waiting...
Device not ready yet, waiting...
ERROR: Device did not become active

Another weird thing about this all: the driver is actually running and is visible in the Activity Monitor as a Core Audio Driver process.

Steps to Reproduce

Steps to reproduce the behaviour (feel free to change the placeholder as you need):

1. Install and Open on Big Sur
2. Sometimes it works, sometimes it does not.
3. Restarted macOS sometimes it let's eqMac launch, sometimes it does not?

Expected behaviour

eqMac should just start every time and work?

Setup information:

• Audio device used for playback: LG Ultrawide monitor (USB-C conencted), Internal Speakers, Headphone Jack connected headphones. Problem is visible without and with devices connected.
• Audio transmission interface: USB-C to Ultrawide
• macOS Version: 11.0 beta
• eqMac Version: v0.3.2
• eqMac UI Version: v1.1.1

If it works sometimes then has nothing to do with Big Sur and is probably related to other issues

Interesting point, I am going to keep my eyes open for any new release on here and will try everything to see once it goes back to work. And I will also try to provide more feedback if I find any more details.

I've also had this issue, albeit consistently, on both betas thus far.

Also have had this issue, consistently on Big Sur 11.0 Beta 4 (20A5343i).

Also have had this issue, consistently on Big Sur 11.0 Beta 4 (20A5343i).

Same here, the terminal output reads:

I have the same issue. Would be great to know if there is anything we can do about it. I really enjoyed the app in the past and would like to use it with Big Sur as well.

Just update Big Sur, audio sounded garbled when using eqMac. stopping (quitting) eqmac, restores the audio back to normal but without the eqmac equalizer setting.
Please help to rectify.

I recently installed Big Sur 11.0.1 and I experienced the same issue where eqMac wouldn't open.

I redownloaded and reinstalled from the official website and that fixed it.

Killing the coreaudiod process seems to always work for me when I have eqMac issues (Big Sur). The process respawns automatically.
