Bug description:
[ Impact ]
* On system with NVIDIA proprietary driver and Bluetooth interface,
when connecting to a Bluetooth headset, after doing a round of
suspend/resume, A2DP interface would be reconnected, but not HSP/HFP.
* This fix is suggested by upstream by reconnecting HSP/HFP (if not
connected) when A2DP is connected.
[ Test Plan ]
* Find a system where NVIDIA proprietary driver is installed.
* Connect it to a Bluetooth headset and see whether the above issue
is reproducible.
* Update bluez from -proposed, see whether HSP/HFP is available and
after switching to HSP/HFP, mic and headphone are both working.
[ Where problems could occur ]
* The changed part would mainly affect the connection of Bluetooth
headset. If the fix brings regression, it would affect the connection
and reconnection of Bluetooth devices.
[ Original issue ]
We found that with certain hardware configs, such as whether NVIDIA
GPU is/is not available (but not always), can affect HSP/HFP profile
after suspend/resume. We will post debug information later on
affected configs.
[Reproducible Steps]
1. Connect Bluetooth headphones
2. Check that Bluetooth Handsfree is available in Sound settings
3. Suspend the system and wake it up
[Expected Behavior]
Bluetooth Handsfree profile should be available after automatic reconnection
[Actual Behavior]
Bluetooth Handsfree profile is missing, one way to make it unreproducible on
the system in question is to use prime-select to switch to Intel GPU:
sudo prime-select intel
