Hydrogen freezes upon saving audio system preferences (Jack)

[masonfeduccia]

Hydrogen version * : 1.1.1
Operating system + version : Win10 Pro 19043
Audio driver + version : Focusrite Scarlett 2i2

---

I'm attempting to connect my MIDI controller to Hydrogen via Jack. When I attempt to set the audio and/or MIDI system to Jack under Preferences and restart the audio driver, Hydrogen becomes unresponsive and I have to force quit. Setting it to PortAudio or PortMIDI works fine, however.

Hi,

having same problem with:
Hydrogen: Hydrogen version * : 1.1.1
OS: Windows 11 pro 22h2
Jack audio: 0.97

My aim is to connect hydrogen with jackaudio patchbay and using the pattern sequencer with redzeppelin Drumkit loaded on Carla.

Thanks

having same problem with

Could you provide a debug log? That would be very helpful for checking whether this is indeed some Hydrogen intrinsic problem or something related to the JACK server.

Does the problem also occur when starting with the -d jack option via the command line?

Did you start the JACK server before starting Hydrogen? Does this make a difference?

Hi,

and thanks for you response and support.

Could you provide a debug log? That would be very helpful for checking whether this is indeed some Hydrogen intrinsic problem or something related to the JACK server.

Hi, i configured the log file to debug but after choosing the jack audio driver

i have only this:

Start logger(E) PortAudioDriver::connect Can't use device '', using default stream�[0m
(E) PortAudioDriver::connect Can't use device '', using default stream�[0m
(E) PortAudioDriver::connect Can't use device '', using default stream�[0m
(E) PortAudioDriver::connect Can't use device '', using default stream�[0m
(E) PortAudioDriver::connect Can't use device '', using default stream�[0m

Does the problem also occur when starting with the -d jack option via the command line?

I can't start jack2 from command line, on windows i'm using qjackctl that embed jack2 driver.

Did you start the JACK server before starting Hydrogen? Does this make a difference?
Sure i always started jack for first. Using Carla have no problems with jack, i think maybe sometinhg wrong after choosign jack driver on hydrogen.

Do you know if there is another way to send you a log? I started hydrogen --verbose debug but haven't something important.

Maybe this could help? jackaudio/jack2#648

[theGreatWhiteShark]

Do you know if there is another way to send you a log?

You can open Windows command prompt (CMD) and enter the following commans (AFAIR this work in PowerShell as well)

start /b "" "c:\Program Files\Hydrogen\hydrogen.exe" --verbose "DEBUG"

I can't start jack2 from command line, on windows i'm using qjackctl that embed jack2 driver.

That's fine too. Do you start QJackCtl before Hydrogen? Is the bug the same if you don't?

Start logger(E) PortAudioDriver::connect Can't use device '', using default stream�[0m
(E) PortAudioDriver::connect Can't use device '', using default stream�[0m
(E) PortAudioDriver::connect Can't use device '', using default stream�[0m
(E) PortAudioDriver::connect Can't use device '', using default stream�[0m
(E) PortAudioDriver::connect Can't use device '', using default stream�[0m

This looks indeed a bit weird and smells like a small bug. But it's most probably not the cause of your problems.

[queengab]

Hi,

thanks for your suggestion.
This is my situation

I started qjacktl then i run hydrogen from cmd.
But i can't see nothing in CMD after launch the verbose option.

Then i have to close Hydrogen and restart it.
If i see my log file i find the same bug reported in the previous post.

If you want i can do more tries if you guide me.
Carla for example works without problem after starting jack.
Maybe it's omething related to how hydrogen comunicate with jack2 on windows? Maybe this version won't work with jack2?

So i'm here please use me to understand what happen

Don't know if in windows system there is something like journalctl

Maybe is a problem related jackaudio and how it start on win? Or this db cache folder?
Maybè @falkTX know something?

[theGreatWhiteShark]

But i can't see nothing in CMD after launch the verbose option.

Yeah. As someone who turns on an old Windows device only once per year this left me puzzled.

Turns the log is only printed into a separate buffer when starting a debug build of Hydrogen using the command I posted. This was working for the Windows bundles I build myself but not for the artefacts we build automatically via AppVeyor.

Anyhow. My bad.

In newer versions of Hydrogen you can use the menu Debug > Open Debug File to display the whole debug log. Not quite sure if this is already supported in your version. Could open the debug file with a recent development version and post the content in here? It will hopefully give us some clues.

If there are other applications working properly with the JACK server, it's more likely this is a Hydrogen-specific problem and too early to get JACK people involved.

I'll check whether I can reproduce these problems. But that might not happen before next week.

Thanks for you work, for hydrogen, it's not really a problem! I want to help as i can.
Anyway finally with your development version (bravo! Gui is improved and it's very pretty), i recorded the debug log:

I can then choose midijack output with my master keyboard, but jack is not initialised.
In this case the software don't freeze.

Thanks very much!

Seem's like from the point of view of Hydrogen the JACK server is in a bad state. And other applications run properly when run right after that?

Could you attach your QJackCtl configuration script and tell me the exact Jack version you are using (and from where you did install it)? I'll try to reproduce it during next week.

In this case the software don't freeze.

But, still, there is no audio driver present and Hydrogen is in a pretty useless state.

Yes for example carla last version work with no problem.
The .jackdrc report: C:/Program Files/JACK2/jackd.exe -S -X winmme -p512 -dportaudio -c32 -i16

This is my qjacktl version:

If i choose jack in preferences than i restart and with jack driver selected...than also this version freeze...so.
We need your help :)

Thanks again!

JACK is pretty dependent on having the same versions of JACK in the client and the server processes. Hydrogen ships with one specific version, and if you have a separate JACK installation if the versions don't match that might be the cause.

It might be worth trying copying the JACK DLL from your JACK install into \Program Files\Hydrogen.

We had thought about using WeakJACK to get around these issues but I don't think that went anywhere due to also having to apply the same thing to PortAudio.

[queengab]

Hi,

thaks for you help:
In my hydrogen folder i have:
libjack64.dll 2.387kb and date 15/04/2022 and Qt5Core Qt5Gui Qt5Network Qt5Svg Qt5Widgets Qt5Xml Qt5XmlPatterns all .dll

In my jack2 folder:
libjacknet64 2.537kb 15/04/2022 and qt5 files inside a sub folder with different "weight"
inside C:\Program Files\JACK2\lib
libjack64.dll.a and some other files with different values

Sure hydorgen come with differnt jack client maybe but what could i overwrite in hydrogen folder?

Maybe hydrogen, in windows like Carla, could come without a jack client embed in its folder?
I don0t know but thanks for your suggestion!

[cme]

Sure hydorgen come with differnt jack client maybe but what could i overwrite in hydrogen folder?

After much faffing about to get a working Windows VM, it looks like the JACK installer is installing libjack64.dll into the Windows directory. So you should be able to just rename the one in the Hydrogen dir to something else (XXXlibjack64.dll :D )

Maybe hydrogen, in windows like Carla, could come without a jack client embed in its folder?

Doing this adds up to the same thing as incorporating WeakJack, with the same issues around PortAudio.

But perhaps we could check for another JACK installation on startup, or something similar. Hmm...

[cme]

Okay, I just tried this on my VM. Installed Hydrogen 64-bit, got a freeze-up on trying to set JACK as the audio output. Moved the libjack64.dll in the Hydrogen directory to a different name, restarted Hydrogen, and successfully switched to JACK.

Interestingly, the PortAudio DLL doesn't seem to reference a JACK dll, and the Windows qJackCtl suggests that JACK is actually using PortAudio as a back-end. So maybe worrying about PortAudio as another JACK client is a non-issue on Windows! That wolud be helpful. I'll look into it a bit more.

[queengab]

Hi!

So thanks! I confirm that if i copy the jackdrive in windows directory to hydrogen directory works!

So this problem can be adjusted..now if i choose on midi system preferences input (my keyboard) output (something) the software frreze.

If i select jackmidi driver withourt selecting input or output, i can se hydrogen on jack patchbay graph and see also it in Carla.
But have also the output L/R to system ouput...

I'd like to configurare hydrogen with jack and carla like this: https://www.youtube.com/watch?v=OeZWMjaAckA
I just figured it out. Don't know why hydrogen have no plugn in to attach red drum and use hydrogen sequencer.

But one thing it's ok, so thanks so much for your effort!!!

[theGreatWhiteShark]

now if i choose on midi system preferences input (my keyboard) output (something) the software frreze.

Could you provide the log output for this new freeze too?

But have also the output L/R to system ouput

There is a checkbox Connect to default JACK output ports in the Audio preferences you can uncheck in case you do not want Hydrogen to automatically connect to your system's defaults.

Don't know why hydrogen have no plugn in to attach red drum and use hydrogen sequencer.

Because supporting (modern) plugins - yet alone different formats - is a massive task. After all, Carla is a full application with quite some lines of source code, which does nothing except of hosting plugins. We do not have sufficient resources to support it ourselves.

Hi this is the log when i try to create this settings

Which verbosity level of Hydrogen did you set when generating this log? I just see two lines logged by Hydrogen and the remainder was done by JACK itself (which seem to restart for some reason). Could you set the verbosity level to Debug (using the -VDebug argument on the command line)?

Does starting Hydrogen/setting its driver to Jack interrupt the audio of other Jack applications?

[queengab]

Very strange now If i try to use jack i have this logs. I'm stuck! Sorry i don't to waste your time.

And finally launching jack as administrator:

[theGreatWhiteShark]

Hmm. Hydrogen log looks similar to the one generated before updating the JACK dll: Hydrogen is not able to connect to the JACK server, starts without an audio driver, and is in a pretty useless state.

`default' server already active
Failed to open server

The log of the JACK server seems to indicate that there was already another JACK instance running on your system which prevented the startup of a new one.
