SER8 - Bluetooth

perceval90

I’ve recently bought Beelink Ser8 8745h, using 2×32 Kingston fury DDR5 5600 RAM and the recent Ubuntu 24.10. Bios version is the recent one, late 2024. The problem is with Bluetooth headphones, usually it works great but when device is put under load, especially stressing RAM memory usage, then Bluetooth bandwidth drops and the sound in headphones is breaking. The same case used to happen to RC mouse when USB receiver was connected directly into SER8. Using usb hub fixed mouse problem but I can’t do the same with bluetooth card that is inside the case.

I think this is known problem across different devices.
Can you please share you insight on what is the reason for this what is the best solution to fix it? Stable bluetooth headphones is one of the crucial functionalities of any PC

Did you even read my problem? I don’t use Windows, drivers are fine, all those boxes have the same problem probably caused by bt/wifi signal interferences. Am asking about your solution to that
