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

          Hi you can resolve this by using a usb bluetooth module if you dont mind they can be had for £3 off aliexpress. I plug mine into a usb hub so i can position it better and it works great. I am using zexmte long range bluetooth 150m range but there are similar ones on aliexpress its using ralink8761b chipset which was plug and play on kde neon linux with liqorix kernel.

          To disable the internal bt first identify the id of the devce with the lsusb command via the terminal, which should produce something like this.

          Bus 001 Device 006: ID 8087:0029 Intel Corp. AX200 Bluetooth

          then create a file using sudo nano /etc/udev/rules.d/81-bluetooth-hci.rules
          and enter SUBSYSTEM==“usb”, ATTRS{idVendor}==“8087”, ATTRS{idProduct}==“0029”, ATTR{authorized}=“0”

          replace 8087 0029 with your values from the lsusb output
          save and close with ctrl o ctrl x
