Description of the problem
A pair of Sony Sony WH-H900N Bluetooth headphones often refuses to re-connect
with a Lenovo V15 G2 ALC laptop. These headphones pair without trouble to a
MacBook Pro and an Android phone.
Step to reproduce:
1. Put the headphones into discovery mode.
2. Go to Settings -> Bluetooth and connect to the headphones.
3. Reboot the laptop.
4. Go to Settings -> Bluetooth
5. Click on the headphones.
6. Try to connect to the headphones.
7. If step 6. fails try to disconnect.
8. Go to step 6.
Expected result:
After step 6 for headphones to be connected and for headphones to announce
"Bluetooth connected".
Actual result:
Sometimes the "connected" slider slides back to unconnected. Sometimes the
slider remains "on" but the headphones don't announce that they are connected
and no headphones appear in sound settings.
How reproducible is the problem:
Fairly reproducible. It can sometimes takes 30 or more connection attempts
before a real connection is established.
