এটি নির্দিষ্ট ব্র্যান্ডের হেডসেটগুলির সাথে বগি। আমি একই সমস্যায় ভুগছি এবং আমার ব্লুটুথ হেডসেটটি পুনরায় সংযোগ করতে এই অজগর স্ক্রিপ্টটি আমার পক্ষে কাজ করে।
কমপক্ষে অজগর 3.5 ইনস্টল করা আছে তা নিশ্চিত করুন। স্ক্রিপ্টটি কীভাবে ব্যবহার করতে হয় সে সম্পর্কে দিকনির্দেশগুলি শিরোনামে স্ব-বর্ণনামূলক:

সম্পাদনা: আমি এই স্ক্রিপ্টটির সর্বশেষ কোডটি একটি অনুরোধ হিসাবে এই উত্তরে অন্তর্ভুক্ত করেছি তবে আমি লিঙ্কটি দিয়ে সর্বশেষ পুনরাবৃত্তি পাওয়ার পরামর্শ দিচ্ছি, কারণ লেখক সর্বদা স্ক্রিপ্ট আপডেট করে চলেছেন।

"""
Fixing bluetooth stereo headphone/headset problem in ubuntu 16.04 and also debian jessie, with bluez5.
Workaround for bug: https://bugs.launchpad.net/ubuntu/+source/indicator-sound/+bug/1577197
Run it with python3.5 or higher after pairing/connecting the bluetooth stereo headphone.
This will be only fixes the bluez5 problem mentioned above .
