Hello! I downgraded linux-firmware package to the original 20240318.git3b128b60-0ubuntu2 version and it does not contain rtw8852c_fw-1.bin.zst file. Therefore kernel module is forced to fall back to older firmware:
[44188.808963] rtw89_8852ce 0000:0a:00.0: probe with driver rtw89_8852ce failed with error -22 [44300.906756] rtw89_8852ce 0000:0a:00.0: Direct firmware load for rtw89/rtw8852c_fw-1.bin failed with error -2 [44300.915449] rtw89_8852ce 0000:0a:00.0: loaded firmware rtw89/rtw8852c_fw.bin [44300.923004] rtw89_8852ce 0000:0a:00.0: Firmware version 0.27.56.13 (ebbe528f), cmd version 0, type 1 [44300.923008] rtw89_8852ce 0000:0a:00.0: Firmware version 0.27.56.13 (ebbe528f), cmd version 0, type 3 And the older firmware is fine. I also tried the latest one with '-1' suffix from linux-firmware git and it does not fix the issue. I've heard that there may be kernel update soon and maybe newer kernel may support firmware '-2'. Maybe it is better. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2137456 Title: rtw89_8852ce: Bluetooth audio lagging/shuttering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-6.14/+bug/2137456/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
