Thanks, for the advice - I had mixed results. What happened was weird - after removing some bloatware and rebooting once or twice, the driver showed up! And, now, there is a new device So, now I can select the driver in Device Setup (see attached screenshots). And, now, there’s a new device in the “WDM Device List” of the ASIO4ALL control panel: “Bluetooth Stereo Audio”, in addition to the “Bluetooth Handsfree Audio”.
In Cubase, I can now select the driver (I attached these screenshots, too) in Device Settings. And, then, in VST Connections (F4), on the Output tab, I can select “Bluetooth Stereo Audio 1 & 2” for the Device Port. And, it works - I can hear output from both instrument and audio tracks…problem halfway solved. But, on the inputs tab, I’m limited to the “Bluetooth Handsfree Audio” selection, which doesn’t work on Inputs (or Outputs, either). So, I think there’s a step that I must still be missing. Some screenshots are attached.
