Public bug reported:
I recently updated to Ubuntu 26.04, and my sound card is no longer working. It
only shows "Dummy Output" in the settings.
My hardware is Intel Raptor Lake (sof-audio-pci-intel-tgl). Even though the
firmware seems to load successfully in dmesg, I get no audio output at all.
This seems like a widespread bug in the current 26.04 development build.
When will an official patch be released for this?
Please fix this as soon as possible.
