Need help with HLC

Yesterday I wanted to load some correction files into HLC, when I discovered that the HLC screen does not appear at all. I use two plugins: U-BACCH and HLC.

The U-BACCH window appears, but the HLC window remains empty. In settings I can configure HLC, but while playing music I cannot switch filters because the window remains empty. Fortunately, HLC works, even though it is not visible.

When I uninstall U-BACCH, the HLC window appears and everything works correctly. The strange thing is that if I uninstall and reinstall both plugins, both plugins appear, but as soon as Audirvana is restarted, the HLC window no longer appears. How do I solve this? It’s not a big problem, except I can’t change filters on the fly.

Hi @Cornelius,

Can you send us a copy of the "Debug Info“ when you have this issue? You can get it in Audirvana Settings>My account.

Note: When you click on the Debug Info button, Audirvana automatically copies all its content. Please paste it in response to this message.

Have you tried to enable the option “Use as Stereo device”?

i tried, but HLC is still invisible

This morning I reinstalled the HLC and U-BACCH plugins in Audirvana and selected “Use as Stereo device” and to my delight everything worked correctly, even after restarting Audirvana. Antoine, thank you very much again for your help
