I can't connect Dell XPS L322x to my bluetooth speakers? On windows 10
From the last month I am playing music via Bluetooth and there is no problem at my side. I am using this speaker model and that is connected via Bluetooth. Something might be wrong on your side. I recommend you to check this article from Microsoft that might help you to sort out this problem.
If the problem occurs again then try to connect any other speakers via Bluetooth. Maybe something went wrong with your speakers.
