Hi everyone,
I’ve received my FW13 AMD on December ‘23, and I’m happy with it.
I’ve only have one “very strange” issue.
My system:
FW 13 AMD 7840U - 32 GB mem, 500 GB SSD SN770
Ubuntu 22.04 LTS - kernel 6.5.0-1011-oem #12-Ubuntu SMP PREEMPT_DYNAMIC
Audio:
- Server Name : PulseAudio (on PipeWire 0.3.48)
- server version : 15.0.0
Bluetooth devices connected:
- Logitech MX Keys Mini
- Apple Magic Trackpad 2 (A1535)
- Bose Headphones NC700
Now, here’s the weird problem:
I’m experiencing, heavy lags on the following devices:
- MX Keys Mini (typing single keystrokes gives: “ssssss llll ooooooo wwwww ” )
and - Magic Trackpad (heavy cursor stuttering and slow delayed responses)
ONLY WHEN my Bose NC 700 is on “Headset Head Unit (HSP/HFP, codec mSBC)” configuration (which means using Headphone and its embedded microphone on a Google Meet for instance).
As soon as I revert my Headphone to “High Fidelity Playback (AD2P Sink, codec SBC)”, Keyboard and trackpad revert to working fine, with no lags.
The thing is: I have a Dell XPS 13 9305 (for work), with the same OS configuration, and I have absolutely no issue with the same devices connected and configured.
So, if anyone has any clue?
Below, here’s what I have found inspecting logs:
