Hello! I’m trying to fix my headphones on my MSI GF63 Thin laptop. My headphones sometimes lose sound. This is happen in random moment and when I step away from the laptop. I tested headphones on other laptops and they worked great! I have a linux60, Intel AX201 Bluetooth, and CGpods X.
P.S. sorry for my English…
P.P.S Im new in linux…
Hello @Skrever and welcome 
And as always… you are not the only one having problems with Bluetooth. Use the search function.
Most likely it is a power saving feature…
Please check the 2 commands and post the output here:
sudo tlp-stat --usb
sudo tlp-stat --pcie
Auto suspend and wake up of usb or pcie can produce the “lose sound” issue. Mostly happening when in battery mode.
This is tlp-stat --usb:

As you can see it suspends. The config file is here: /etc/tlp.conf with all default variables. Lines starting with # are comments, so be ignored.
You can edit it directly with root permissions or create a folder:
sudo mkdir -pv /etc/tlp.conf.d/
and put a text file in it with the variables you have set:
sudo nano /etc/tlp.conf.d/usb.conf
nano is a terminal text editor. You use any editor you like.
Put there in:
USB_BLACKLIST_BTUSB=1
That will exclude bluetooth for auto suspending.
Just to be sure, restart your laptop and check again with: sudo tlp-stat --usb.

It took me 4 tries to get my bluetooth headphones to pair. It would either find them and not pair or not find them at all.
What I had to do was to turn bluetooth off, turn my headphones on and then restart bluetooth, then I was able to successfully pair them.
No, my headphones successfully connect to my laptop. But they freeze when I step away from it.
YES!!! It’s amazing! My TLP was not turned on! Thank you man!!!
