I have an old laptop HP pavilion g4 and have dual boot setup on it. The laptop has INTERNAL bluetooth + wifi combo adapter Qualcomm Atheros AR9485. Everything used to work fine in windows until a few months (around 2021) when a windows update came and the bluetooth stopped connecting in windows.
In case of ubuntu, bluetooth will only connect once when computer is booted initially,
Once connected,
- If some form of audio is playing, when the connection is established initially, then it'll stay connected for the duration of which the audio stream is playing,
- While the audio is playing, it plays in slow volume (even at max out volume, it plays at around 30%)
- once the audio stream to the bluetooth device stops, then in and around 5-6 seconds, the device disconnects, and stays that way
- bluetooth settings menu becomes unresposive. and the toggle switch for bluetooth stop responding.
So, recently I bought an external bluetooth adapter TP-link ub500 and installed it in windows and it works fine there but, in case of Ubuntu, it had the same connectivity issues listed previously. So I followed several links and tried different solutions.
In Ubuntu 20.04 firstly,
- I tried the top answer of this question which didn't work,
- then i found out that support for ub500 was added in Ubuntu 22.04 so I updated my pc to that version.
Now, in Ubuntu 22.04 the same problem persists Everything listed above except the low volume issue which was resolved.
Then I checked lsusb to see if it was displaying the adapter, which it was
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 006 Device 029: ID 0cf3:311d Qualcomm Atheros Communications Bluetooth
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 002: ID 046d:c534 Logitech, Inc. Unifying Receiver
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 003: ID 05c8:0348 Cheng Uei Precision Industry Co., Ltd (Foxlink) HP Truevision HD
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 002: ID 2357:0604 TP-Link TP!Link UB500 Adapter
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Then ,I thought that pc was using the internal adapter instead of the external one
- so I tried this solution, but then too the issue was present.
- So I used
bluetoothctlto check which device it was using and found that it was using the external adapter which I confirmed by comparing the MAC address of both the internal and external device.- Installed and updated bluez.
In the end, after all that, the problem still persists and I am not sure how should I approach this now.
