Did a little research on this one because of having some stuttering issues when I'm connected with any speaker/headset on the Huawei Matebook d15. After troubleshooting, updating, and re-installing the Bluetooth hardware none worked.
What I found out was an online article that some laptops are using the same frequency for wifi and Bluetooth connection which causes interference, I did some experimenting on my own, and when the laptop doesn't use the wifi the stuttering is gone..
Some solution that I stumbled upon was changing the wifi bandwidth connection of my router. So I connected my laptop to the 5ghz and tried listening to some music, it helped a little when the wifi traffic is not heavy, but it did not totally eliminate the stuttering. My last hope is to buy a Bluetooth adapter online, hoping it will have a smooth connection. Will comment back again if none worked and if the Bluetooth adapter works smoothly.
*Not an expert in computer hardware, but I hope it gave you some idea, just assuming the research that I did is correct hahah. This issue is a hassle!
