Bluetooth prompt error at startup

Prompt the following information when I turn on my PC. But I didn't notice anything unusual when using it.

1/13/22 2:23 PM    kernel    Bluetooth: hci0: Failed to read codec capabilities (-56)
1/13/22 2:23 PM    kernel    Bluetooth: hci0: Failed to read codec capabilities (-56)
1/13/22 2:23 PM    kernel    Bluetooth: hci0: Failed to read codec capabilities (-56)
1/13/22 2:23 PM    kernel    Bluetooth: hci0: Failed to read codec capabilities (-56)
1/13/22 2:23 PM    kernel    Bluetooth: hci0: Failed to read codec capabilities (-56)
1/13/22 2:23 PM    kernel    Bluetooth: hci0: Failed to read codec capabilities (-56)

Finally, what can I do to get rid of the prompt?

Re: Bluetooth prompt error at startup

I have the same messages, is bluetooth provided by iwlwifi on your system ?

See https://wiki.archlinux.org/title/Silent_boot for methods to silence various things including messages like these


Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
Did you use the guided installer ? If yes, I can't help you.

Hi, I use wired network, so I don't have iwlwifi.
This information was only available after I updated the system on the 1/13th.
Current System Version: 5.16.0-arch1-1.

Re: Bluetooth prompt error at startup

Many wireless chipsets also provide bluetooth, you may have iwlwifi loaded without realising it.

The messages occurred first on my system with kernel 5.16.0 , not with 5.15 kernel .

Please post lspci -k (run as normal user, not sudo or root) so we can verify what chipset / kernel module takes care of bluetooth on your system.

Re: Bluetooth prompt error at startup

I'm seeing the same with kernel 5.16.
Relevant kernel.org thread.
Fix in 5.17 tree.
