[Solved] No sound from laptop to Bluetooth speakers

[Aily]

I've got:
Bluetooth speakers
Lenovo ideapad 110
18.2 Sonya MATE

Problem: Even though my laptop find my Bluetooth speakers, the sound won't come from my Bluetooth speakers but from my laptop's speakers. It may be something simple, but my knowledge is quite limited when it comes to computers so my hopes are that someone here knows what may be wrong and what I need to do to get to sound transferred to my Bluetooth speakers.

Thank you!

I would try

Code: Select all

wget https://gist.github.com/pylover/d68be364adac5f946887b85e6ed6e7ae/raw/bbba417cae1419ed35b79c1ac400c7197a12e2fc/a2dp.py

Code: Select all

chmod +x ./a2dp.py

Code: Select all

./a2dp.py CC:C5:0A:69:80:3E

See if that script can get it working

[Aily]

It worked like a charm. Thanks a million!

Keep that last command handy, you are likely to need it again
