Bluetooth earphone is connected but disconnected immediately. [Intel 3165]

[이야기]

I have erased and reinstalled Pulseaudio.
It seems like this can not be done since.

I tried the following.
sudo apt-get remove alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio

I did this again.
sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils
sudo apt-get install linux-sound-base alsa-base alsa-utils
