Hello Prashant, thanks for submitting a bug report. Here's the changelog for linux-firmware in Jammy (22.04 LTS): https://launchpad.net/ubuntu/jammy/+source/linux-firmware/+changelog
It looks like there may have been changes to the MT7921 code in the following versions after 20220329.git681281e4-0ubuntu3.26: - 20220329.git681281e4-0ubuntu3.27 - 20220329.git681281e4-0ubuntu3.29 So it's possible that one of these versions introduced a change which caused their Bluetooth to stop working properly. Would it be possible to get the tag number they tested from upstream? That may be useful to find a version of linux-firmware that works after 3.26. Thanks! ** Changed in: linux-firmware (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2098088 Title: bluetooth functionality for mediatek wifi/BT module MT7921AU does not work with latest firmware package on x86_64 platform To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/2098088/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
