A2DP Bluetooth audio choppy sound

I am happy to use the Cowin E7 headset for listening music from my old iMac with Debain 10. However, the connection is going to choppy after I pause audio play from time to time.  With Google uncle's help, I'v found the site which gives me the clear resolution askubuntu.com/questions/475987/a2dp-on-pulseaudio-terrible-choppy-skipping-audio

 

We can do this in both ways : command line and GUI.

 

 

 

$ pactl list | grep -Pzo '.*bluez_card(.*\n)*'

Name: bluez_card.FC_58_FA_88_32_63
	Driver: module-bluez5-device.c
	Owner Module: 32
	Properties:
	  ......
	Profiles:
     ........
	Active Profile: a2dp_sink
	Ports:
		headset-output: Headset (priority: 0, latency offset: 0 usec)
			Part of profile(s): headset_head_unit, a2dp_sink
		headset-input: Headset (priority: 0, latency offset: 0 usec)
			Part of profile(s): headset_head_unit

 

Here the important parts are Name and headset-outpu latency offset. I changed the latentec 10 ms

 

pactl set-port-latency-offset bluez_card.FC_58_FA_88_32_63 headset-output 50000 
sudo service bluetooth restart

 

It can be changed via pavucontrol
