Boot up the affected machine 2. Check the audio output by pressing `Test speakers` on the g-d-d sound menu. 3. Press the speaker and mic mute keys and verify the following    - Speaker muted: LED is on    - Speaker not muted: LED is off    - Mic muted: LED is on    - Mic not muted: LED is off [Where problems could occur] This change is restricted on particular SSIDs. Should be no risk of regression. -- PR: Noble: https://kernel.ubuntu.com/forgejo/kernel/linux-firmware/pulls/393 Resolute: https://kernel.ubuntu.com/forgejo/kernel/linux-firmware/pulls/394 To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/2158858/+subscriptions
