Hi Milky, encounter another problem when I turn on my desktop. After login into windows breakaway prompt 'Error starting audio engine. Requested output device doesn't exist'. Then the Setup Wizard page pop-up, I can see the output device as "Bluetooth Audio", went on to select 'Buffer Size" after which it prompt me to select "Breakaway Pipeline" as default sound device in control panel. But now headphone has no audio. Kindly advise how to resolve this issue, thanks.
