Hello. I am having MAJOR issues with my bluetooth audio stuttering in Windows 11 with my Sennheiser Momentum 4's.
Firstly, I'd like to start that this only started happening after I updated to Windows 11. I was using Windows 10 beforehand but decided to update it due to the EOS in October. Furthermore, this was a clean install of Windows 11, meaning I reset my PC first- that wouldn't be an issue. I checked for system file corruption regardless but there was none. I was using them on Windows 10 for months prior without issue. My PC has 1TB of memory for the new OS to run on with 32GB of RAM, and a Ryzen 5 5600x CPU too.
I have removed and re-paired the headphones. In the Bluetooth services tab of my Momentum 4's properties I have turned of Hands-free Telephony and Remotely Controllable Device. I went ahead and moved the port that the bluetooth adapter was plugged into- twice.
I have checked for driver updates for both the bluetooth adapter and headphones. I have also uninstalled and reinstalled all drivers, including for my bluetooth adapter. I was recommended to turn off Bluetooth Audio Gateway Support in the Services settings, and that still didn't work.
I am on a PC ran with an ethernet cable and no motherboard Wi-Fi capability or adapter, so no Wi-Fi interference could be happening. I have also checked every other device I use with bluetooth and even gone as far as turning it off on those other devices. I sit within one meter of the bluetooth adapter.
I restarted my PC when making any and all of these changes, and none of them have worked.
The audio stuttering is extremely irritating as it happens multiple times a minute, whether I'm watching a video, on a call or listening to music etc. I am left totally unsure what to try after all of this, so I have decided to ask here. If anyone is able to give advice to try and help fix my problem I would be extremely appreciative. Thank you in advance.
