Then do the following: First make sure that sound comes through your BT phones when using other apps. Then open the Windows Sound Settings (on the taskbar is a little speaker icon, right click on that). Then look for the BT phones device and click on the Device Properties, a new window opens, look for the Advanced Properties, click on it and yet another window opens. In there choose the Advanced tab. There you find the option “Allow applications to take exclusive control”, make sure that that option is NOT selected. Also check for the default sample rate and remember. Close all the little windows and start Dorico, go to Edit > Device Setup. In there set the sample rate to the same value as you just remembered. Next, choose the Generic Low Latency Driver and then click on the Device Control Panel button. Yet another little window opens. At the top is an option called “Allow ASIO host application to take exclusive control of the selected port configuration”, also this one, make sure it is NOT selected. If that is the case, in the middle of the window is a listbox with output ports, your BT phones shall turn up there by now. Make sure that they are checkmarked at the front, then close that window. Also close the Device Setup dialog and reload your project, after that Dorico shall put sound out through your BT phones.
This is the general advice for BT headphones on Windows. I will revise the text and make it available in the FAQ section.
And here the advice for OSX:
First make sure the BT headphones are connected and sound comes through from other apps like e.g. iTunes.
Then start Dorico and go to Edit > Device Setup. In that dialog under ASIO Driver in the drop down list now your BT headphones should turn up. Most likely - and this is important - you will see two device entries. E.g. for a Sennheiser HD 4.50 BTNC the entries “HD 4.50 BTNC” and “HD 4.50 BTNC (2)” are to be found in the list. Why 2 devices? Most BT headphones also come with a built-in microphone, so you can also use it as a headset in conjunction with a smartphone. So the first device is the microphone of the headset and the second device is the earphone. Dorico can’t make any use of the microphone, so in Dorico you always have to choose the second device in the list. So in short, choose your correct device from the list, close the dialog and that should be it, Dorico then shall play out via your BT headphone. We can’t guarantee things to be as simple for every BT headset out there. Post in the Dorico forum if you are having trouble.
