I am using wemeet-bin for online classes. I found that the sound of Linux version is very awful, but on Windows it is good. There is much grrrr sound. And I found that when I change my bluetooth headphone to HFP from default A2DP, it will be much better.
Update:
I changed to pipewire from this solution:
Update solution
sudo pacman -R manjaro-pulse
sudo pacman -R pulseaudio-alsa pulseaudio-bluetooth pulseaudio-ctl pulseaudio-zeroconf
sudo pacman -R plasma-pa
sudo pacman -R pulseaudio
sudo pacman -S manjaro-pipewire
sudo pacman -S plasma-pa
Now I use A2DP+AAC, it is perfect like on Windows
Here is a comparison and explanation from Philips Audio for different profiles:
HSP (Handset Profile) – provides the basic functionalities needed for communication between a handset (cell phone) and a headset - mono Bluetooth headset operation.
HFP (Hands Free Profile) – has somewhat extended functionality to HSP and was originally intended to control a cell phone from a stationary, in-car, hands-free unit - required for typical, mono Bluetooth headset operation.
A2DP (Advanced Audio Distribution Profile) – allows the transmitting of stereo audio signals (with much better quality than the mono encoding used for HSP and HFP).
AVRCP (Audio / Video Remote Control Profile) –is used for sending commands (e.g. Skip Forward, Pause, Play) from a controller (e.g. stereo headset) to a target device (e.g. PC with Media Player).
If the headset is mono or stereo, there will be a difference depending if using the proper profile or not.
