I’m not getting sound during play back with a newly installed version of Dorico on Windows 11. I’ve been searching the forums for a solution but I’m not getting anywhere. I’ve installed Halion and I can get it to open as a standalone program, but it seems like there is an issue with Dorico communicating with Halion. In the Play tab, Halion appears with two !! on either side. Any help would be greatly appreciated.
Those !! marks tell you that Dorico cannot find Halion Sonic.
Try reapplying the Playback Template (Play>Playback Templates…)
If that fails, do Help>Create Diagnostic Report and upload the zip file that appears on your Desktop so the team can help you.

Here’s the Diagnostics zip.
This is what I see in the playback templates. Which one should I select?
It doesn’t matter, they all use Halion. Applying any one will clear out existing sounds and reload.
Still seeing the same thing in the play tab (!! HALion Sonic !!).
Then you’ll need patience until the team responds.
Gotcha, thank you! 
Hi @Ben_Jervis , welcome to the forum.
The thing in your case is following:
You have a MS Surface which has an ARM processor. Applications that are built for the old intel processors need to get specially adapted and translated in order to run on an ARM processor, but there is also an emulation mode where you can run old Intel code on an ARM processor. This emulation costs a some additional cpu cycles, but other than that has no impact.
Now, Dorico is not yet ARM compatible but can run in emulation. HALion Sonic is already ARM compatible and does not need the emulation. But this is where it does not fit, a Dorico in emulation mode can not load a plug-in that is ARM compatible.
So the solution is, first uninstall HALion Sonic and then reinstall it again, but instead of the ARM version you need to install the x64 version of it. In that case both, Dorico and the HALion Sonic plug-in run in emulation mode and everything will be fine.
To uninstall HALion Sonic, go to the Windows Control Panel, look for the Apps tab and in the list of installed apps find Steinberg HALion Sonic 7 and on the right side click on the 3 dots and then from the pop-up menu choose uninstall.
Once that is done go to this webpage and from there download and install the Win x64 version of HALion Sonic. That should be it.
In case not, please go in File Explorer to %appdata%\Steinberg\Dorico/ 6/ AudioEngine_64 and from there delete the folder Dorico 6 AudioEngine VST3 Cache and then restart Dorico.
Hi Ulf!
Thanks for the response. When I try to install the Winx64 version of HALion I get a error message about my computer not meeting the minimum system requirements (see attached). I appreciate your help!
Hi Ben, which Windows version do you run?
Windows 11.
