<![CDATA[Audio driver could not be opened]]>I compiled stand-alone app 3 times, using HISE export, Projucer, and Hise-Exporter. I am using the up-to-date Scriptnode branch.

Regardless of which one I used, neither resulted in an app that plays back the sound. I get the warning upon opening exe file:
"Audio driver could not be opened".

The last time I compiled a standalone app, it had a nice little menu on top where you could specify the driver etc, but that is no longer present. The app used to have a nice window heading, but now it looks like a typical Windows app header.

On top of that, the midi channel list floating tile contains no data.

In my custom settings panel, I have everything to do with the audio driver set to false.

I saw this issue reported in 2018, but it seems to have crept back.

Any solutions to this issue?

Cannot get the same sound on 2.0. I don't know why. (at some point Harmonic Filters were updated to monophonic I guess)

I imagine the differences lie in the XML only so it should be editable

Original project lacks of CustomSettings panel (Audio driver, Output, sample rate, etc) and I want to add it but... No matter what I do, I always get an "audio-driver-could-not-be-opened" dialog on Standalone compiled instrument

Any clue?

including the driver settings in the GUI panel enabled me to change it after the fact and solve the issue.

I told you to do that 3 days ago :p

I'll try that. @d-healey Yes, I deleted all old stuff and recompiled HISE. Let's see if including an audio device in the settings on GUI will fix the issue.

I've experienced it with some of my test users. If they try to open the standalone, it may default to some weird audio device that shouldn't be used and it throws an error and breaks the app until you pick a proper audio device. Windows is pretty bad about this. If you add a Settings floating tile to your interface you can correct it by just changing the Audio Device right from the exported plugin.

Are you guys compiling the standalone apps with no issues?

Yup, did you get rid of your extra versions of the source code yet?

Seems like I'll have to go back and recompile using older versions of HISE to demonstrate. It has definitely been there.

@gorangrooves Ah I see, was this just a Windows thing?

theres no audio settings in the top left of any stand alone windows app I ever built...

It seems I deleted previous version I had, as it was not the final software version. The controls do not get put over your GUI. They get included in the build-in menu of the app header. Any Windows app has a header and part of the header is where this menu is found (at least it used to be).

but they have been available by default in compiled standalone apps.

Got a screenshot? As far as I know there are no default controls put onto your UI.

There is supposed to be a little audio settings menu by default (top left, if I remember correctly). It is not there now and the app throws an "audio driver could not be opened" error upon initializing.

@Christoph-Hart Do you know what is going on here?

That hasn't been there since HISE verion 1.6 or something. You have to add it in the custom settings floating tile to access those settings.
