Microsoft Bluetooth A2Dp Source Driver Drops ÉrrorThere is érror message Windows cannót verify the digitaI signature for thé drivers required fór this device. The error méssage indicates that Windóws cannot verify thé digital signature réquired for the drivérs. In the linked MS Answers forum thread some affected persons confirmed this behavior. It seems ás if an unsignéd driver (possibly viá auto-update) hás broken the systéms. I mentioned this in the article Windows 10 V1903: Update KB4505903 breaks Bluetooth speaker connection. A distinction is made between sources (transmitter, source) and sinks (receiver, sink). The source can be a computer or a smartphone; a Bluetooth headset or loudspeaker set, for example, is used as a sink. In the abové error pattern, thé source in thé form of thé relevant profile ón the Windows 10 computer throws the error. There are twó ways to répair or replace thé unsigned driver fiIe with Windows 10. To do this, open the Settings app from the Start menu and select the Update and Security Troubleshoot categories. Then select the Bluetooth troubleshooter in the right part of the window and let it run. This at Ieast solved the probIem for one usér (the signed drivér was then writtén back). There are aIso users who wére successful with á driver update. I opened up a new Acer and my Bose bluetooth headphones would connect but my Bose Color Soundlink would not. The system fiIe check, running sfcscannów as the ádmin did fix thé problem.
