No Playback - RealTek High Definition Audio

Dear Ulf,
As requested, you can see nothing is apparently wrong and Realtek audio is showing up.
It’s not in the Dorico Asio setup…

Thanks, I didn’t know that one.

Okay, then please check the following: In the taskbar on the right is a little speaker symbol, right click on it and choose “Playback devices”. Select your Realtek speaker device, click “Properties” and in the Properties window choose the “Advanced” tab. Is the “Allow applications to take exclusive control of this device” option ticked?
It is ticked on my computer and if I untick it, then also the device won’t appear anymore in the Generic Low Latency Driver panel.

If still a problem, may I suggest that you download the ASIO4ALL driver from http://www.asio4all.com and try with that one?

Press Win+R hotkey, type “devicemgr.msc”, then press Enter.
This works with all versions of Windows based on NT technology.
