Overview: There are many Windows 10 users who are facing Bluetooth audio lag issue while using Bluetooth speaker or headphones with Dell/HP/Lenovo/Acer/Asus or any brand PC. Today in this post we will follow troubleshooting steps to fix Bluetooth audio lag issue on the Windows 10.
So, let’s start with real user’s practical scenarios!
Scenario 1: Bluetooth audio syncing issue
After updating to Creators Update my CSR 4 Bluetooth dongle has delays with sound after some hours. A Xiaomi Bluetooth speaker connects to it, and after some hours sound gets out of sync and I have to restart AudioSrv, particularly AudioEndPointBuilder service and sound gets correctly synced again, but after another hour, it gets to present the same syncing issue again. I have tried with drivers provided by Windows Update and also the drivers from the manufacturer which is CSR Harmony Wireless Software Stack Cinolink BT403 Drivers-20161123T051246Z. Both of them didn’t help to fix this issue. I don’t know if new spatial sound or atmos Dolby feature has to do something with it, but I also tried to disable them (set to None). However, it was of no help. When using Linux on this same machine (dual boot), sound works well without that syncing issues even after a long period of usage. Since I delete Windows. old I cannot rollback to Anniversary Update, so I’m afraid to reinstall Anniversary and end up again with Creators Update. Is there any way to lock Windows Anniversary Update so it would not update to this unwanted update?

Scenario 2: Bluetooth audio lag on windows 10…
I know I can’t be the only one who experiences this because I have tried several different Bluetooth headsets and speakers on multiple PC’s, laptops, and even a surface pro 4. For music, it’s not big deal because you can’t really realize the delay. However, watching videos or playing a game it becomes extremely noticeable. It’s generally a lag of about somewhere between 250-500ms as a rough estimate based on adjustments through VLC and Kodi. This seems to be the case for all devices on all systems. I even came across an open source Bluetooth fix, which made it slightly closer and has gone through tons of forums saying to turn off power management for the Bluetooth and disabling audio enhancements… However, there’s always a lag (had the same issue on windows 8). Also, when I use my android tablet or phone, there is no noticeable delay with any of these devices. If it helps, I’ve tried using power beats Bluetooth headphones (firmware up to date), some generic Bluetooth headphones, Amazon Echo, and Amazon Tap. Each seems to have the same delay. I know I can adjust audio sync manually in programs like Kodi or vlc, but I’m not looking for a “band-aid” fix. Especially since I primarily use Plex to stream my personal content (which does not have an audio sync setting). This is clearly a windows issue since I have no delay when connecting to non-windows devices. With all that said, does anyone have any other ideas or possible solutions to this issue?
