I have modified files, installed applications (VLC, Blueman, oFono), looked around for drivers and have made no progress After going through so many changes, I concluded that this needs to be fixed by Canonical/Ubuntu. I have gone through this URL & other links this URL refers to. Neckband: Boult Audio ProBass FlowX, Bluetooth 5.0 Laptop hardware: Dell Inspiron 3543 Intel(R) Core i5-5200U CPU 2.2 GHz x 4 8GB RAM 1 TB HDD So, the microphone in the neckband works fine. I thought I received a defective neckband but when I paired the it with my Android mobile and made a call, the other person confirmed she could hear me. I recorded video footage but the footage has no audio looks like no input to the microphone. The earphones work fine but the microphone doesn't. I could connect the neckband to my laptop effortlessly. So, to circumvent the usage of the integrated microphone, I ordered a Bluetooth neckband with earphones and microphone. I did these things and the static may have reduced but it is still there. Some posters suggested killing PulseAudio, specify the correct audio sample rate etc. I looked around in Google to see if there is a solution to my problem. To me, it feels like the integrated microphone has a driver issue. BTW, I use application guvcview to access my integrated webcam to record footage. Maybe, behind the scenes, my headphones + microphone use the same integrated microphone and/or its drivers to record. When I play back the footage, it has static. I used a pair of headphones + microphone to record a short video message. My laptop currently has Ubuntu Linux 20.04 64 bit. 2020 IIRC, I had to record a short video message and I realized that the footage has static. This laptop came with an integrated microphone. I own a Dell Inspiron 3543 laptop since June 2015.
