I understand it might not be a specific Silverblue issue, but more likely a Fedorao-wide or linux-wide driver problem typically encountered with new hardware. But I’m interested to see how layering drivers on top of the OS image works on Silverblue.
I have this brand new Thinkpad X1 Yoga Gen 4, kind of similar hardware than the X1 Carbon Gen 7. I’m running Fedora Silverblue 30.1.2. Note that I had to rollback to overcome another problem with the wireless card, but the audio behaves as described
below, whatever the version.
-
The audio gets loud and does not vary in volume whatever the position of the cursor on the volume slider, except in the off position where it behaves as expected.
-
The mic is not detected in Settings/Sound/Input
