Hello there ,
I am using latest Pop! OS(22.04) , and i am having issues with connecting my bluetooth headset to my laptop, (Works on win11 tho),
I have searched through youtube videos and even system 76 troubleshoot website, none of those work
Bluetooth sometimes gets connected by it doesn't recognise it as headset, so it is not displayed in sound settings
output of inxi -A:
Audio:
Device-1: NVIDIA driver: snd_hda_intel
Device-2: AMD Raven/Raven2/FireFlight/Renoir Audio Processor
driver: snd_pci_ps
Device-3: AMD Family 17h HD Audio driver: snd_hda_intel
Sound Server-1: ALSA v: k6.12.10-76061203-generic running: yes
Sound Server-2: PipeWire v: 1.0.3 running: yes
 


if it works in windows and not linux then we know it's not a hardware issue. couple questions:
  1. is the bluetooth adapter built into the laptop or is it an external/usb antenna (like those usb dongles you see with logitech devices)?
  2. what is the make/model of the laptop?
  3. what is the make/model of the headset?
  4. when you look in lsusb and lspci, what is the hardware id for the bluetooth device?
 
This may help.

Thread 'Troubleshooting Bluetooth'

Here are some things to try.

The first one here is obvious, but you never know. Not all computers support bluetooth. Does yours?
NOTE:** Bluetooth usually doesn't work from a VM. **
Code: 
lsusb | grep -i blue
Code: 
lspci | grep -i blue

One of those two commands should return some device of some kind. If not, you likely don't support bluetooth.

Code: 
sudo systemctl status bluetooth

If it isn't running...

Code: 
sudo systemctl enable bluetooth
sudo systemctl start bluetooth

If it's not installed, you can try to install bluez, it's more or less the standard tool for bluetooth in most...

1.The bluetooth is internal adapter, it is a mediatek one
2. My laptop is lenovo loq 2024 one model- 15AHP9
3. The headset is CMF buds pro 1,
4. idk why but i run lsusb / lspci , it is not giving any output, but i also found out through hwinfo in win11 that, my bluetooth adapter is in a usb port

It should tell you something like "USB Linux generic root hub" or similar.

The thing is, it is an MediaTek chip with both wifi and bluetooth capabilities

Foxcon Hon Hai is not MediaTek, different company, different drivers.

ok thanks! so yeah, it looks like that's commonly used in conjunction with the MT7921 chipset, and it has had kernel support since v5.15, but there's some compatibility issues on multiple distros --> https://linux-hardware.org/?id=usb:0489-e0cd

did a little bit of research & it looks like you'll want to delete your bluetooth pairing config (if it exists) in linux, reboot, get into the bios, disable fast boot & set your suspend state to S3, then in linux try to re-pair the bluetooth device.

alternately, this may work:
Code: 
usb_modeswitch -R -v 0489 -p e0cd

if nothing else, stop using PopOS - it's known to be problematic on non-System76 built computers.
