Karlston Posted August 24, 2019 Share Posted August 24, 2019 Microsoft: Win10 1903 having problems with Bluetooth speakers This one’s odd. According to the just-posted KB 4518538, “Bluetooth speakers don’t work after update 4505903 is installed on Windows 10, version 1903.” After you install update 4505903 on Windows 10, version 1903 on a computer that has an internal speaker installed, you experience one of the following issues: A Bluetooth speaker can’t connect to the computer. A Bluetooth speaker can connect to the computer. However, the speaker output sounds noisy (bad quality). A Bluetooth speaker can connect to the computer. However, the sound is generated by the internal speaker instead of the Bluetooth device. Additionally, in Device Manager, you notice an entry under the Sound, video and game controllers node for Microsoft Bluetooth A2dp Source that shows a yellow bang (exclamation mark) icon. Here’s what’s odd. KB 4505903 is July’s “optional non-security” second monthly cumulative update. I have no idea why the second July update would have a problem that doesn’t occur in the first August cumulative update. (We haven’t yet seen the second August cumulative update for Win10 1903.) UPDATE: @abbodi86 has what sounds like the right diagnosis: The issue is probably caused by some combination, or bad sequence, of patches. It does not seem directly related to the update Source: Microsoft: Win10 1903 having problems with Bluetooth speakers (AskWoody - Woody Leonhard) Link to comment Share on other sites More sharing options...

Ha91 Posted August 27, 2019 Share Posted August 27, 2019 Nope. I can confirm now that my bluetooth earphones are no longer pairing with my laptop, but they are with my old phone that has not been updated in at least a year 🤣 Link to comment Share on other sites More sharing options...
